Adafruit 954 USB serial cable
The Adafruit 954 USB serial cable can be used to:
- Power the Raspberry Pi
- Have console access via a serial port (built-in Prolific USB emulator and e.g. PuTTY on Windows laptop)
When using the Adafruit 954 USB cable on Windows 7 the Prolific driver seems already be installed, so you could skip this step. Simply connect the USB cable. You will see a device Prolific USB-to-Serial Comm Port; verify via Control Panel → System → Device Manager to get the port number.
The cable can be ordered via internet.
Transparent case for the Raspberry Pi model B+ is too low
There are some problems with the transparent case of Raspberry Pi B+:
- The case is too low for the Adafruit 954 USB serial cable; it bends the circuit pins
- The latch does not close properly
- There is no spare hole for the cable
Bug Check: DRIVER_IRQL_NOT_LESS_OR_EQUAL
This indicates that a kernel-mode driver attempted to access pageable memory at a process IRQL that was too high. Possibly the Prolific driver contains a bug.
