A note about this page: For USB devices, please specify if they required a powered hub
19-Apr-2012: Now that the Model B board is shipping, details added should relate to this board and the default Debian distribution unless stated otherwise. A suggested suffix markup scheme is as follows:
- (A) - Relates to model A production board
- (B) - Relates to model B production board
- (!) - Information from alpha and beta board days -- beta board verified peripherals should still apply to production boards for the most part, but the alpha board is fairly different
- No markup - relates to all production boards
If you are adding to a product list it would help clarity if entries are kept/added in alphabetical order.
Power Usage Notes
|Warning:||Adding peripherals may increase the loading on the power supply to your board and this, in turn, may affect the voltage presented to the Raspberry Pi. If the Raspberry Pi's supply voltage falls below a certain value (anecdotally stated as around 4.75 V), or it begins to fluctuate, your setup may become unstable. There is a Wiki section about this issue which is worth a read.|
Model B Hardware Revisions and USB Power limits Hardware Revision 1.0 The original Model B board had current limiting polyfuses which limited the power output of each USB port to approximately 100 mA. USB devices using more than 100 mA had to be connected via a powered hub. The Raspberry Pi's PSU was chosen with a power budget of 700 mA of which 200 mA were assigned to the USB ports, so the Raspberry Pi's (poly)fuses were designed only for devices up to 100 mA, and typical 140 mA polyfuses will have as much as 0.6 volt across them when drawing currents near the 100 mA limit. As a consequence the USB ports are only directly suitable for "single current unit" USB devices which, according to USB specifications, are designed to work with just 4.4 Volt. Not only do non single current unit devices draw more current (causing greater Voltage drops, and greater stress on the fuses), they also might require 4.75 Volt to work.
Model B Hardware Revision 2.0 and Revision 1.0 with ECN0001 change This had the polyfuses removed, removing the 100 mA current limitation for each USB port (but leaving the main fuse F3 intact). Users should still ensure their power supply can power the Raspberry Pi and the USB peripherals. Revision 2.0 was released in August 2012. Warning: Because the polyfuses have been removed, back feeding of the PI, by applying power via its normal USB output, can damage D 17 if triggered by an over-voltage, and so lead to consequential over-heating. This can be discovered by melts, scorching, smoke or worse.
Linux Driver Issues
Shortly after the Raspberry Pi was released it was confirmed that there were a number of issues with the Linux USB driver for the SMSC95xx chip. These included problems with USB 1.x peripherals that use split transactions, a fixed number of channels (causing problems with Kinect) and the way the ARM processor handles the SMSC95xx interrupts.   A large number of fixes were included in the 2012-08-19-Wheezy-raspbian Linux image.

- E1820 Works on Raspbian with Sakis3G
- E220 installation instructions
- E353 HiLink Works on Raspbian
- E160 (AT commands only)
- E169, E620, E800, (12d1:1001) - works on Raspbian Wheezy, details here
- AirCard 250u works with wvdial/network manager
- AirCard 320u (0f3d:68aa) works in WWAN mode, driver provided by the kernel. Tested on Arch.
- Kernel version 3.10 has a bug that causes the WWAN interface to never be in RUNNING state (no carrier). Use 3.6 kernel instead.
- AT command guide can be found here
- for GPS to work you have to enable it. First, setup the modem (guide here) and after that enable NMEA output by passing nmea=1 parameter to the sierra kernel module. Warning! Enabling NMEA output may cause the modem to drop connections / restart itself. This is probably related to higher power drain. This may not be the issue when a powered hub is used.
- 307 Works fine with Sakis3G script. The connection LED does not change its state after establishing a connection but the same behaviour on a normal linux system.
- AirCard 340u (Netgear/ATT Beam) works with latest GobiNet/GobiSerial code on Raspbian and 3.10.25+ kernel. Requires firmware update from Netgear to disable Windows 8 support and make it autoconnect. guide here.
- ZTE MF190S
- ZTE MF626
Works fine with Sakis3G script. You can use force it to ALWAYS be in modem mode (See here: http://forums.whirlpool.net.au/archive/1205127 ), or use usb-modeswitch ( as described here http://blog.christophersmart.com/2009/05/21/telstra-nextg-working-with-mf626-usb-modem/ )

- Vodafone MD950 (1dbc:0005) - is working on RPi (Raspbian Wheezy) but not out of the box, more details here.
USB Sound Cards
You will usually want the
alsa package for sound. In the Debian image for Raspberry Pi (and possibly other distributions) USB sound cards are prevented from loading as the first sound card, which can be an annoyance if it's the only device you have. To disable this behaviour edit
/etc/modprobe.d/alsa-base.conf and comment out the last line;
options snd-usb-audio index=-2 . If you are not user pi you may need to add your username to the audio group thus:
sudo adduser yourusername audio (user pi usually belongs to this group anyway).
- Logitech G930 Wireless Gaming Headset with 7.1 Surround Sound (stereo works with ALSA, have not tried 7.1 Surround Sound)
- NuForce uDAC-2
- Plantronics Stereo USB Adapter -01 (works with ALSA) (shows up in lsusb as 0d8c:000c C-Media Electronics, Inc. Audio Adapter)
- VIGO USB Soundcard, black - Device ID: 0d8c:000e ("C-Media Electronics, Inc. Audio Adapter"). Working, but on Raspbian 3.6.11 it fills up kern.log with "cm109_urb_irq_callback: urb status -71" messages. To prevent this, you can insert `:msg, contains, "cm109_urb_irq_callback" ~´ as first rule into /etc/rsyslog.conf.
- Aureon Dual USB (not with USB high speed; add dwc_otg.speed=1 to /boot/cmdline.txt, but that will slow down all USB transfers)
- Texas Instruments PCM2704
Databases of supported sound cards
Class compliant USB sound cards
Any USB1.1 audio interface that is class compliant should work with Linux, same goes for USB2.0 interfaces that adhere to the current USB audio standards. There are some interfaces that are supported in Linux while they do not comply to the standards because specific quirks have been added to the USB Linux drivers. To verify if your interface is supported search for a manual of your interface and check if it needs drivers to run under Windows/Mac. If the manual explicitely mentions no drivers are needed the interface is almost surely a class compliant device. When in doubt check the aforementioned databases.
If you encounter problems setting up your USB soundcard check the RPi Wiki article in the linuxaudio.org Wiki: http://wiki.linuxaudio.org/wiki/raspberrypi

USB TV Tuners and DVB devices
- DVB-T205, based on rtl2832u chipset, worked with this driver on older 3.2 kernel. Couldn't get same device working reliably on current kernel. (On the older 3.2 kernel it worked with Saorview (Irish DTT service), both HD & SD.)
- TV28T v2 USB DVB-T & RTL-SDR Receiver, RTL2832U & R820T Tuner, MCX Input. DVB-T works with OpenElec 4.2.1 connected to the PiHub, tvheadend backend + frontend, finds all expected, non-encrypted channels in the south of Germany. I did not try to use the remote.
- Hauppauge NOVA-T Stick (Revision 70xxx) DiBcom DiB0700 chipset, requires powered hub.
- Hauppauge NOVA-TD Stick (Revision 52xxx) DiBcom DiB0700 chipset, requires powered hub.
- Hauppauge WinTV-HVR-1950 (tested analog tuner with omxplayer, tested Digital OTA with MythTV)
- Hauppauge WinTV-HVR-950Q (tested Digital OTA with TVHeadend in Raspbian)
- K-World UB499-2T Dual DVB-T USB Tuner. IT9137 chipset. With no other USB devices connected Raspberry Pi can just about power this stick. IR and supplied remote work with XBMC.
- Technisat_SkyStar_USB_HD. Instructions: http://www.linuxtv.org/wiki/index.php/Technisat_SkyStar_USB_HD Used the Raspberry Pi to receive and redirect it via network to another host. Didn't try to play back the stream on the Raspberry Pi itself. Tested with Astra 19.2E radio and SD-TV channels
- TT-TVStick CT2-4400 USB Fernbedienung rev2. DVB-T works with OpenElec 4.9.4 BETA connected to the PiHub, tvheadend backend + frontend, finds all expected, non-encrypted channels in the south of Germany. DVB-C also works, finds around >30 TVs and >100 radio stations. I did not try to use the remote, nor did I listen to any radio station. TV works, SD channels are ok, HD channels jitter. tvheadend backend crashes often within OpenElec 4.9.4 BETA, but restarts, so still buggy but looks good(BETA!). It did not work out of the box with the stable OpenElec 4.2.1.
- DVB-T USB Dongle (Silver casing), based on AF9015 chipset.
- DVB-T USB Dongle, based on RTL2832 FC12 (HD/SD), IR was detected, but it is not tested.
- HDTV USB DVB-T dongle, based on IT9135. This tuner comes in two revisions. Revision is printed on PCB.
- rev. 1.0; should work with 3.2+ kernel, need confirmation.
- rev. 2.0; works with kernel 3.6.11, without a powered hub. This tuner also requires a firmware (dvb-usb-it9135-02.fw) which can be downloaded from this page. It's in Hungarian, so google translate or equivalent is recommended. The remote also works.
According to this post, there may be issues on some software configurations when using omxplayer.
USB Video / Frame grabbers
- EasyCAP DC60 (STK1160 chip) - works out of the box for older versions of Raspbian. If you're getting grey stripes see this tutorial

USB GPS devices
- Columbus V-800 (MediaTek (MTKII) 3329 GPS chipset) - does not require powered USB hub. Works on Wheezy (using gpsd & gpsd-clients)
- Royaltek RGM 2000 SiRF2 using the included serial (TTL) to USB - converter (Prolific pl2303-chip)
- Garmin eTrex Vista HCx: It works, but it may draw too much power. To get it working (software part): https://wiki.openstreetmap.org/wiki/USB_Garmin_on_GNU/Linux
- GlobalSat BU-353 Does not require a powered hub, works fine when directly plugged into the Raspberry Pi. On Raspian, requires the gpsd and gpsd-client packages. For some reason, the gpsd daemon does not always start correctly on boot. You may need to do something like the following to manually restart it:
sudo killall gpsd; sudo gpsd /dev/ttyUSB0 -F /var/run/gpsd.sock
- GlobalSat BU-353-S4 supports two protocols: NMEA, and SiRF v4. NMEA works fine, but SiRF v4 isn't compatible with "gpsd"'s SiRF v3 interpreter, resulting in a greatly reduced data rate (as low as four location fixes per hour). To keep "gpsd"'s autoconfiguration from putting the receiver in SiRF mode, you'll need to pass the "-b" flag when starting "gpsd".
- GlobalSat BU-353 Does not require a powered hub, works fine when directly plugged into the Raspberry Pi. On Raspian, requires the gpsd and gpsd-client packages. For some reason, the gpsd daemon does not always start correctly on boot. You may need to do something like the following to manually restart it:
- WBT-200: No problem on Debian
- Holux M-215: Works fine on Arch, uses Silicon Labs CP210x RS232 serial adaptor driver
- Bluenext BN903S: No problem on Debian image (19-04-2012).
USB UART and USB to Serial (RS-232) adapters
A USB UART adapter is used to access the serial console of the Raspberry Pi from a development host such as a laptop or desktop PC. The USB end connects to the PC and the UART header end connects to the USB. While it is possible to connect the USB end to another Raspberry Pi, this configuration has not been tested unless explicitly mentioned against an individual entry below.
Working USB to Serial Adapters
- FTDI (Future Technology Devices International Limited)
- FT232 chip based adapters works for some people, but others find it hangs Linux when the port is opened. The module is ftdi_sio.
- FT232R USB UART works out of the box between Raspbian Wheezy and OS X Mavericks (Product-ID: 0x6001, Manufacturer-ID: 0x0403, Maximal Speed: 12 MBit/s, Maximal Power Consumption: 90 mA).
- FT2232D dual RS232/FIFO works (used in various JTAG devices)
- PL2303 chip based adaptors works fine on latest Debian tested with minicom, gtkterm and screen.
A USB to Serial (RS-232) adapter is used the other way around, ie. the USB end connects to the Raspberry Pi and the RS-232 end (DSUB-9 or DSUB-25 pin) to the other device which may be another computer, (old) modem or printer, or some electronic test equipment.
- "Best Connectivity" (Possibly also sold under the "Newlink HQ" or "Kenable HQ" labels)
- FG-U1232-PL2 Based upon the Prolific PL2303X chipset and listed by lsusb as
ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port. Appears as
/dev/ttyUSB0, and requires the user to be a member of the dialout group (which pi is for Raspbian Wheezy). Initially tested using an old RS Datalinker setup in "loopback" mode via microcom upto 9600 baud, and gtkterm after installing that from source code. All handshake lines toggled as expected and no characters were lost. Subsequently gtkterm was used to check bi-directional communication with an ancient brother EP44 electronic typewriter (as a printer/dumb terminal) at 1200 baud. Signal lines were again monitored with the Datalinker.
- FG-U1232-PL2 Based upon the Prolific PL2303X chipset and listed by lsusb as
- "PL2303HX USB to RS232 TTL Converter Adapter Module" on dx.com: http://dx.com/p/pl2303hx-usb-to-rs232-ttl-converter-adapter-module-164590
- Based on the Prolific PL-2303HX chipset. Listed by lsusb as ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port. Appears as /dev/ttyUSBX with GUID dialout so your user has to be in that group. If not, sudo usermod -a -G dialout yourusername will add your user to the dialout group. Works great with screen /dev/ttyUSBX 115200 to connect from your workstation to your RPi.
- Belkin F5U409 Works OOTB; does not support speeds above 115,200, so you can't use it for DMX or other high-speed protocols.
Problem USB to Serial Adapters
- CH340 Chipset - Currently not supported by RPi but there is a patch of kernel code here, but it is for a 2.X kernel. If you find you have bought one of these, then it may work under Windows, but as of writing there is no support for RPi. Otherwise you can have a go at getting the patch to work.

PS2 / AT to USB Converters
- Unbranded active converter known as the "blue cube". Based on the Cypress CY7C63723C 8 bit RISC. Please see http://geekhack.org/showwiki.php?title=PS2-to-USB+adapters for more information.
Note that although the adapter might work, PS/2 keyboards were not designed to be low power USB devices, so they might not meet the requirement to work with considerable lowered supply voltage (4.4 volt) provided by the USB ports of the raspberry PI. These keyboards should work when powered by a powered hub.
Tested PS2/AT keyboards
All above tested with the famous "blue cube" on a powered USB hub.
- IBM Model F (please note requires an additional AT to PS2 converter)
- Dell AT101w
- Northgate Ominikey Ultra T (please note requires an additional AT to PS2 converter)
- 04d9:1400 Holtek Semiconductor, Inc. PS/2 keyboard + mouse controller
- Working: Ipex RT215KTW PS/2 keyboard
- Not working: HP SK-2502 PS/2 keyboard (gets power, but it does not init - three LEDs remain permanently lit. Keyboard + Holtek converter work on a Linux PC, although this keyboard doesn't work with some native PS/2 ports.)
The Raspberry Pi does not have a power on/off switch as standard (it does have a reset switch), however some add on boards have been developed to cater for this need.
- The Pi Supply Switch is an on/off power switch for the Raspberry Pi which includes a hard on and off switch and a soft shutdown switch for the Pi, making it easy to manage power on your Pi. They were recently successfully funded on Kickstarter.
- RemotePi Board
- The RemotePi Board is an intelligent infrared remote controlled power switch add-on board for the Raspberry Pi. It allows to switch power on and off using any button (configurable in learning mode) of an existing standard IR remote. Power is only cut after notifying the OS and giving it time to shut-down. It is mainly intended to remote control (using LIRC) and power off/on a mediacenter system. i.e OpenELEC, Raspbmc, XBian, RasPlex, Raspbian. The board is compatible to simple GPIO IR receiver and piggy backs onto the Raspberry Pi, no soldering required. For more information click here.
The Raspberry Pi uses a standard Micro USB (type B) power connector, which runs at 5 V. Generally you can use a MicroUSB to USB cable and then either power the Raspberry Pi directly from your main computers USB ports (if they provide enough power), or by using a USB to Mains adapter. A number of mobile phones use MicroUSB power cables, and these are compatible with the Raspberry Pi in most cases. Below is a list of power adapters known to work.
Working power Adapters
There is now a 5.25V 1500mA power supply manufactured specially for the Raspberry Pi to account for voltage drop due to the high current draw of the Raspberry Pi when compared to typical (phone charging etc.) duties.
Available in UK, EU, USA and AU varieties from Pi Hut and Pi Supply
- 5.25 V 1 A Model 501 (Newark 44W4932) USB 110-240 VAC power supply [4.99-5.01 V @ T1/T2 with 100 mA BT and/or mini wireless-n on RPi USB ports]
- 5 V 2.5 A Model AP5A - Charger/switching with 7 connectors(also Microusb)

Note that apple designs its charger products to work optimally as chargers. In practice this means that apple chargers drop their output voltages somewhat with output current, so that the charging circuits do not need to dissipate more heat than is strictly necessary. Because of this, and although many people have reported apple products to power their basic PI setup reliably, its still not an optimal choice for a PI system that uses power hungry USB devices. Also, because of the popularity and high price of these chargers there are many very sub standard, but almost impossible to recognize as fake copies on the market, and some of these fakes are about the worst things you can try to power your PI with! Not only do they not work, they may actually be dangerous to use!

LCD touch screen add-ons
Note that active converter boxes may draw power through the HDMI port, and thus will put an extra load on your PSU, and also increase the current running through the Raspberry Pi's primary input fuse. HDMI ports (and the raspberry PI) are designed so that they deliver a very limited amount of power (50 mA) to the TV/Monitor/display-adapter and much more isn't in theory allowed. In fact there is a diode (D1) in series with the power line which can only handle 200 mA, if the adapter tries to draw much more than that the diode might fail. Therefore only externally powered adapters are to be recommended. Despite this, many people report success with non externally powered devices. If you have bought a non externally powered HDMI to VGA adapter, and you experience problems with it (It behaves badly, D1 burns out, F3 "blows", or your PSU overloads), then not all is lost, there are cheap (a few dollars) adapters that allow you to add external power to the HDMI cable! An example can be found here: .
HDMI to DVI-D cables, or HDMI cables with an DVI-D adapters should work, connected to a DVI-D monitor, that is because both HDMI and DVI use the same kind of digital signaling (LVDS). The only limitation being that DVI-D misses the signal channel for audio.
There are three kinds of DVI. There is DVI-D, a digital signal fully compatible with HDMI, so a passive cable can be used. There is DVI-I, which is a connector with both analog pins and digital pins. An HDMI to DVI-D adapter fits in a DVI-I female connector. Finally, there is DVI-A. This a fairly rare connection, but occasionally it will be found on some monitors and is an analog interface, in fact the same as VGA! In any case, you may need to change config.txt hdmi_force_hotplug=0 to =1 if your display does not receive DVI signal (the analog output is likely active).
Some adapters like Farnell part AK-CBHD03-BK are HDMI to DVI-I, which, while not fitting in a DVI-D monitor, are still compatible. The analog pins simply must be bent.
The HDMI to DVI-D cable provided by Apple with the 2010 Mac Mini worked. It does not appear this adapter can be purchased separately.
- The Pi Hut
- HDMI to DVI Cable for the Raspberry Pi (from The Pi Hut's Raspberry Pi Store)
- Other Variants
- AmazonBasics HDMI to DVI Adapter Cable (model SK231) works and is inexpensive.
- A generic HDMI-to-DVI converter from eBay. Works well, but it's probably the cause of some power loss between the Raspberry Pi and the monitor, causing this problem. A setting of config_hdmi_boost=5 in /etc/boot solved this. Note that config_hdmi_boost=4, as suggested in the troubleshooting guide, helped, but it did not solve the problem completely.
HDMI to VGA cables do not work! They rely on logic incorporated in a video card that isn't available in a PI. Somehow such a video card outputs analog signal on the otherwise purely digital HDMI connector, that seems to be the only way for it to work. But normally HDMI cables never carry analog signals and the PI surely doesn't output analog signals either, almost no HDMI output device does, as its completely against HDMI specifications.
HDMI->VGA converter boxes
HDMI to VGA converters do work, they convert the digital serial data streams from HDMI and using complex logic, and digital to analog converters they convert the HDMI signal to the analog signals needed for VGA, and sometimes also convert HDMI audio to an analog stereo signal. But note that if they feed off the PI it can cause a problem, as the PI only is designed to provide about 50mA to the (HDMI or DVI-D) monitor, and these adapters use >200mA, while the absolute maximum the PI can let through is 200mA. These adapters also thus use about half the energy that the PI (without USB devices) uses. Therefore its much better to use an adapter that has an external power input. Alternatively there are HDMI dongles (male to female HDMI adapters) that have a barrel input connector to feed the adapter with.
It seems unlikely any of these HDMI->VGA converters could be used for driving a SCART RGB SD CRT TV with a suitable lead (as shown here for ATI/Nvidia PC output http://www.mythtv.org/wiki/RGB_Scart) because they only output preset progressive resolutions, whereas the TV will need an interlaced resolution and probably custom timings.
Most will require use RPi_config.txt. Start off with hdmi_safe=1.
HDMI to VGA + audio adapter from DHgate
- Under six pounds with free international shipping  makes this worth the delivery time of just under 3 weeks. Works out of the box at 1024x768 without editing config.txt (I'll try editing for full HD later). Spec. says upto UXGA and 1080p with 10-bit DAC at 165MHz/1.65Gbps. Raspberry "tvservice -a" reports that it supports audio up to 192k at 24-bit. Sounded fine on my tiny speaker. Comes with 3.5mm stereo plug-to-plug cable and USB to mini barrel jack power cable which it doesn't need on the Pi. Ran mine for ages without the external power and the Pi's HDMI regulator never got more than 34 degrees C. Adapter weighs only 14.8g and can plug directly into the Pi or even via a 90-degree 'elbow' which I prefer to use. VGA signal is good enough to run 2 displays at once using a cheap splitter cable. After brief testing with good headphones, it seems there's some definite noise on a signal of 17,500Hz and 18,500Hz is distorted. In contrast, the RPi's own analogue sounds clean at 17,500Hz. So you couldn't consider this an alternative to a good USB DAC.
HDMI to VGA Cable adaptor from amazon
- At under ten pounds this one  is one of the cheapest, but perhaps due to a more advanced design is seems power frugal enough to most often work well with a Pi, it has many comments saying it works well with the Pi, and gives tips on how to edit config.txt.

"Neewer" HDMI to VGA
- http://www.amazon.co.uk/gp/product/B007KEIRNG -- "Neewer" HDMI to VGA -- some issues discussed below:
According to user "Tom1989" the same Neewer HDMI to VGA adapter burned out BAT54 Schottky diode D1 on the Raspberry Pi and broke its HDMI output: Serious HDMI Problems. What's that smell? Burning Raspberry!. On that thread, "mahjongg" suggested the NXP (or equivalent) PMEG2010AET as a high-current replacement for D1. The PMEG2010AET has 1 A max forward current, much greater than the BAT54's 200 mA limit which may be exceeded by your HDMI -> VGA converter. Remember that the converter's current must come from your Raspberry Pi power supply and go through the Micro USB cable and polyfuse F3, so you may get extra voltage drops and/or cause F3 to trip depending on how much current the converter uses. As always with board modifications, YMMV. Also on the same" thread, user "pwinwood" reported the Neewer's current to be 400 mA, which is twice the limit of BAT54 diode D1. "pwinwood" also took the Neewer apart and added its own +5 V connection adapted from a USB cable, which bypasses Raspberry Pi's Micro USB cable and polyfuse F3.

HDFury1 1080p HDMI to VGA Converter
- HDFury1 1080p HDMI to VGA Converter from HDFury.com. I'm not sure the HDFury1 can be got a hold of easily nowadays, I happened to have access to one to try out. HDFury2, 3 and 4 are available as far as I can tell, but it is very pricey compared to the alternatives. HDFury1 was around £80 when we bought one for a project at work. HDFury2 seems to be around £130, 3 and 4 are getting on towards £200 or more. So not to be recommended as a solution unless you happen to have one lying around. I don't believe there is any relationship between the company that produces these and the HDFuryPro I bought for myself (See above). I didn't alter any config settings, just plugged it in. It doesn't work without having its external power supply connected, as it requires 0.4 A, which is too much draw for the 5 V supply available from the HDMI socket on the Raspberry Pi. Its power LED lights, but no picture is produced. In comparison to the HDFuryPro this picture from this device is sharper, but it is not enough to justify the extra cost.
The config.txt settings used are:
hdmi_drive=2 hdmi_group=2 hdmi_mode=36 disable_overscan=1

HDMI - VGA [lontium chip]
- http://cgi.ebay.pl/ws/eBayISAPI.dll?ViewItem&item=251086464644. It is very cheap, but it works perfectly. No config.txt changes was needed at all. I've booted Raspbian and OpenELEC. Monitor is detected correctly and the optimal resolution is set (Raspbian) or you can change the res in the menu (OpenELEC). The /opt/vc/bin/tvservice is able to read monitor edid data. I tested the adapter using NEC 72VM 15" LCD. (1280x1024 60 Hz, 1024x768 60 Hz, 640x480 works) The adapter is based on Lontium LT8511A chip, but I was unable to get the specification for it. The D1 diode is getting very hot though. Most likely the adapter drives more than 200 mA. The standard RS Components 1.2 A USB power supply is able to provide enough power for the Raspberry Pi and the adapter. I'll try to modify the adapter to connect external power to bypass D1.
Pi-View HDMI-VGA converter
- The "Pi-View" was designed specifically for use with the Raspberry Pi. It does work although the small box gets warm and the video output isn't great (slightly fuzzy text, smaller screen area even with overscan enabled) 
DVI-D -> VGA active adapters
None are currently listed
SCART adapters (SCART plugs with three RCA connectors in the back), will probably work when used with the yellow RCA plug connected to the Raspberry Pi's RCA video output. Additionally using a splitter cable (3.5 mm jack plug on one end, and red-white RCA plugs on the other end) will probably work when plugged into the red and white (left and right audio channels) of the SCART adapter.
