Running with: Linux quadrio.nederware.nl 3.15.0-031500rc1-generic #201404131835 SMP Sun Apr 13 22:36:23 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
But didn't help. 1. I first upgraded to latest 14.04, then rebooted. No webcam found after reboot. 2. Then installed the new kernel, still no webcam found. 3. I then turned off the computer, waited a while, and turned it on. Skype recognised webcam for a few milliseconds, then video crashed. After the crash I rebooted, webcam not found. Turned it off, waited, and on again, wecbcam found. It seems that after a crash I need to physicall turn off the computer before lsusb sees the webcam. This is what it sees after I've turned off the computer: Bus 002 Device 004: ID 17ef:480c Lenovo Integrated Webcam That device simply is not found after the crash.
