I have added a Creative Labs Live! Optia webcam to my Debian Squeeze machine and can see it using lsusb.

Unfortunately, when I use uvcdynctrl -l I get the message No Devices Found

I am on Kernel version 2.6.32 which I understand contains the uvc drivers.

Any ideas?

This question came from our site for system and network administrators.

Just because the kernel has the source for a driver doesn't mean that driver was included in the build. First try lsmod | grep uvc to see if the uvc module is currently loaded, if not try modinfo uvc to see if you have it. – Kevin Jun 26 '12 at 2:09

Yes, your kernel contains UVC but have you build them (or creators of Debian)? You should check module as Kevin wrote, next driver may be compiled in the kernel, so check config: grep USB_VIDEO_CLASS /usr/src/linux/.config. When you'll have driver running, some webcams needs firmware at least.
