Hi Laurent,

I send you  log file with trace (kernel 2.6.30.9)

I have tried this kernel (on UBNT RouterStation and OpenWrt) with results:

2.6.28.10. -  camera works, I tried only snapshots (I have to use 
external power for USB, without  external  power  sometimes works, 
sometimes  no ...)
2.6.31.5 - kernel copmpiles ok, but uvcvideo module was missing, I don't 
know why ...

Thanks,

Martin
