You have been subscribed to a public bug: My webcam was working well in previous releases of Ubuntu. It even worked well during installation of 12.04 and I could take pictures for my account ".face", but It doesn't work after restarting to installed system. I couldnt take any picture from cheese or VLC with the message "No device found". I searched for the device in /dev/ directory and there was no video0 node. I searched for that in Intermet and I found this page: http://forums.debian.net/viewtopic.php?f=6&t=71236
I made the node and gave access to it with this commands, but nothing happened: sudo mknod /dev/video0 c 81 0 sudo chmod 666 /dev/video0 Then I called the module "gspca_vc032x " with: sudo modprobe gspca_vc032x and opened cheese. It worked, the webcam LED turned on and I had picture for about 5 seconds and after that it doesn't go on at all. I tested removing and recalling the "gspca_vc032x " module twice, but there were no point. this is the tail of dmesg: [53572.344148] usb 1-3: new high-speed USB device number 14 using ehci_hcd [53572.538802] uvcvideo: Found UVC 1.00 device HP Webcam (5986:0137) [53572.541535] input: HP Webcam as /devices/pci0000:00/0000:00:12.2/usb1/1-3/1-3:1.0/input/input22 [53573.412176] hub 1-0:1.0: port 3 disabled by hub (EMI?), re-enabling...
