Fujitsu Siemens Pocket Loox C550

Linux port status

Kernel: 3.8

What works

  • Basic functionality
  • USB host
  • USB OTG
  • LCD
  • Touchscreen (need improvements)
  • All buttons including power button
  • limited SD card
    • technically: only when SD is used right before kernel boot, then regulator gives power to SD slot and it works
    • simple: you need to boot from SD card or someway utilize it until kernel boots

Hardware
