Hello,
I'm trying to make my new webcam work with uvcvideo. The model I use
should work fine according to the hardware compatibility list.
Unfortunately, this is not true in my case.
This is what dmesg says after I plug in the camera:
usb 1-2: new high speed USB device using ehci_hcd and address 3
usb 1-2: configuration #1 chosen from 1 choice
v4l1_compat: module is already loaded
videodev: exports duplicate symbol video_unregister_device (owned by
kernel)
usbcore: registered new interface driver snd-usb-audio
v4l1_compat: module is already loaded
videodev: exports duplicate symbol video_unregister_device (owned by
kernel)
uvcvideo: Found UVC 1.00 device <unnamed> (046d:0994)
videodev: "�2�" has no release callback. Please fix your driver for
proper sysfs support, see http://lwn.net/Articles/36850/
input: UVC Camera (046d:0994) as /class/input/input9
usbcore: registered new interface driver uvcvideo
I haven't found any program that would detect the camera. Tried Cheese,
Ekiga, Skype, Kopete and VLC... All of them either crash or freeze. This
is what I see in dmesg when I try to open the camera with VLC:

I use a vanilla kernel 2.6.27.17 with Reiser4 and Suspend2 patches. My

According to the device list, this webcam should just work. So there
must be something I'm doing wrong. A piece of good advice would help me
a lot.
