I have the same problem with Mustek gSmart 300 in Jaunty RC. Mustek gSmart 300 is basically a webcam that was made to look as a digital camera, has a very small inbuilt memory enough for taking 20-30 pictures of 640x480. But the webcam functionality is the main reason people bought it. When the webcam is pluged-in it shows almost the same behavior as described in bug report #291906 (Mustek gSmart 300 not working in Ubuntu 8.10) which was marked as duplicate of bug #285682 (Ubuntu 8.10 can't mount digital camera showing a window popup message: -60 could not lock the device message). This time there is no window popup message: -60 but there are 3 beeps. The end result is that the camera is properly detected, but no /dev/video0 is created. We can see this from
dmesg ... [59707.024530] usb 2-2: new full speed USB device using uhci_hcd and address 52 [59707.322348] usb 2-2: configuration #1 chosen from 1 choice [59707.325155] gspca: probing 055f:c200 [59707.327177] gspca: probe ok [59707.327245] gspca: probing 055f:c200 [59708.523532] gspca: disconnect complete As you can see the device is probed twice, and after the second probing there is some kind of disconnect. lsmod | grep gspca gives gspca_spca500 21632 0 gspca_main 29952 1 gspca_spca500 videodev 41600 1 gspca_main I found a temporary solution by removing gspca modules from the memory and then installing them again by: sudo rmmod gspca_spca500 sudo rmmod gspca_main sudo modprobe gspca_spca500 After this is done, there are no multiple beeps, and dmesg gives: ... [60252.278571] usbcore: deregistering interface driver spca500 [60252.280145] spca500: deregistered [60252.282087] gspca: main deregistered [60252.306251] gspca: main v2.3.0 registered [60252.307925] gspca: probing 055f:c200 [60252.309122] gspca: probe ok [60252.309139] gspca: probing 055f:c200 [60252.309168] usbcore: registered new interface driver spca500 [60252.309173] spca500: registered This time /dev/video0 is properly created and the webcam works under skype. It has other problems under cheese, kopete, vlc etc. which I presume are related to other kind of bugs. The second temporary solution I found was to kill /usr/lib/gvfs/gvfs- gphoto2-volume-monitor process before pluging the webcam into the computer. I didn't post my comment under bug #285682 because the discussion over there is mostly related to digital cameras and not webcams and secondly because there was a heated discussion and someone stating that this is completly normal and this is how things should be, resulting in bug #285682 status marked as invalid . Please don't forget that Mustek gSmart 300 is basically a webcam with a very low sensor resolution. Can this kind of "multifunctional" webcams be blacklisted from the gvfs or gphoto2 modules? p.s.
