Having seen a video.c update, I thought I would have another go at seeing
whether the camera (which works when booted into windows) would magically
start working, but no joy. Maybe I'm missing something?

Booted with -vx, but there are no complaints.

  2200   2200 videoctl CALL  open(0x41f3,0,0x7f7fffffed03)
  2200   2200 videoctl NAMI  "/dev/video0"
  2200   2200 videoctl RET   open -1 errno 5 Input/output error

Thoughts?

Cheers,
