Description Andrei Voropaev 2012-01-11 08:44:08 UTC

After booting kernel version 3.1.6-gentoo the UVC camera Logitech E3500 has stopped working. Neither built-in microphone, nor the video are responding. The /var/log/messages contain following entries

kernel: uvcvideo: Found UVC 1.00 device <unnamed> (046d:09a4)
kernel: input: UVC Camera (046d:09a4) as /devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.1/1-1.1:1.0/input/input7
kernel: usb_audio: Warning! Unlikely big volume range (=3072), cval->res is probably wrong.
kernel: usb_audio: [5] FU [Mic Capture Volume] ch = 1, val = 5888/8960/1
kernel: uvcvideo: Failed to set UVC probe control : -110 (exp. 26).
kernel: uvcvideo: Failed to query (GET_CUR) UVC control 3 on unit 1: -32 (exp. 1).
kernel: uvcvideo: Failed to set UVC commit control : -110 (exp. 26).


Reverting back to version 3.0.6-gentoo fixes the problem.

Reproducible: Always

Comment 1 Andrei Voropaev 2012-01-26 11:23:30 UTC

Shortly after the problem, the PC has died and was taken for repair. When I got it back, everything is working again. So, possibly the problem was caused by hardware failure which happened when the newer kernel was running.

I'm closing this report. Hopefully, I'm doing it in correct way :)
