Hi,
I use MSI StarCam Racer on Debian Linux Lenny 2.6.26-1-686 and video
works without problem:
usb 4-4: New USB device found, idVendor=0c45, idProduct=62e0
usb 4-4: New USB device strings: Mfr=2, Product=1,SerialNumber=0
usb 4-4: Product: USB 2.0 Camera
usb 4-4: Manufacturer: Sonix Technology Co., Ltd.
I plan use this camera on OpenWrt, (UBNT Router Station, kernel
2.6.30.9) and kernel didn't open this device:
Linux video capture interface: v2.00
usbcore: registered new interface driver uvcvideo
USB Video Class driver (v0.1.0)
usb 1-1: new high speed USB device using ar71xx-ehci and address 2
usb 1-1: configuration #1 chosen from 1 choice
uvcvideo: Found UVC 1.00 device USB 2.0 Camera (0c45:62e0)
uvcvideo: No valid video chain found.
Do you have any idea?
Thanks and best regards,
Martin

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.

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?
Thanks.

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

Thanks. The log shows that your problem comes from UVC descriptors parsing.
This has been fixed in 2.6.31, so you should upgrade to at least that version
or install the latest uvcvideo driver.

Check that the uvcvideo driver is selected using make menuconfig.
