Public bug reported:
I have a HP dv6835nr with a Microdia Sonix built-in webcam (ident code:
0c45:62c0) which doesn't work under Lucid 10.4.
uname-a gives:
Linux laptop 2.6.32-23-generic #37-Ubuntu SMP Fri Jun 11 07:54:58 UTC 2010 i686
GNU/Linux
cat /proc/version_signature gives:
Ubuntu 2.6.32-23.37-generic 2.6.32.15+drm33.5
relevant dmesg extract shows:
[ 1838.273185] usbcore: deregistering interface driver uvcvideo
[ 1843.113280] Linux video capture interface: v2.00
[ 1843.117712] uvcvideo: Found UVC 1.00 device USB 2.0 Camera (0c45:62c0)
[ 1843.118464] uvcvideo: UVC non compliance - GET_DEF(PROBE) not supported.
Enabling workaround.
[ 1843.118838] uvcvideo: Failed to query (129) UVC probe control : -32 (exp.
26).
[ 1843.118844] uvcvideo: Failed to initialize the device (-5).
[ 1843.118914] usbcore: registered new interface driver uvcvideo
[ 1843.118919] USB Video Class driver (v0.1.0)
I have no /dev/video* and webcam doesn't work with cheese, luvcview, or
anything else I could find.
I recently received this computer so I don't know if it's a regression,
but I'd guess that it is. As the dmesg output above shows, I've tried
removing and reinserting uvcvideo via modprobe to no avail. I'm not sure
if this bug is related to bug #435352, though unlike this bug, other USB
devices don't seem to be affected - they work fine.
