Re: MSI StarCam Racer - No valid video chain found
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 Laurent Pinchart napsal(a): Hi Martin, On Monday 02 November 2009 21:31:50 Martin Rod wrote: Hi Laurent, I send you output of lsusb. I think, that the uvcdriver is the latest. I try older kernel tomorrow. Could you please load the driver with trace=255 (modprobe uvcvideo trace=255) or, if the driver is already loaded, change the trace parameter to 255 (echo 255 /sys/module/uvcvideo/parameters/trace), plug your camera and send me the messages printed by the uvcvideo driver to the kernel log?

Hi Laurent,
I send you output of lsusb. I think, that the uvcdriver is the latest. I
try older kernel tomorrow.

Hi,

I plan use this camera on OpenWrt, (UBNT Router Station, kernel

Do you have any idea?
Have you tried upgrading to a more recent kernel, or to install the latest
uvcvideo driver ? If the latest driver still doesn't work, please send me the
output of
lsusb -v -d 0c45:62e0
using usbutils 0.72 or newer (0.73+ preferred). Thanks.
