Ok, this is really strange. I have two Linux system, a desktop and an eeepc, both with openSUSE 11.2 (the desktop has the X86_64 version) and when I first tried the NX-6000, I had the same messages on both system. Here are the one from the desktop: Dec 1 00:43:29 linux-l8hb kernel: [165305.462577] uvcvideo: Found UVC 1.00 device Microsoft® LifeCam NX-6000 (045e:00f8) Dec 1 00:43:29 linux-l8hb kernel: [165305.462899] uvcvideo: UVC non compliance - GET_DEF(PROBE) not supported.

I didn't reboot my PC or change kernel version. I still have m friend's lifecam cinema here, and it still works perfectly (so I don't think it's a messed-up configuration). Any hint?
