On kernel torvals/linux.git next branch, it doesn't even really connect, on 3.13 (which I'm running on my laptop) I get errors like this: xhci_hcd 0000:00:14.0: ERROR Transfer event TRB DMA ptr not part of current TD when running uvccapture. When running e.g. cheese or the like, the screen stays blank. uvccapture also reports: ioctl querycontrol error 22 and then the kernel message repeats forever, while I can't even exit uvccapture unless I kill it hard, at which point I get xhci_hcd 0000:00:14.0: Signal while waiting for configure endpoint command usb 1-3.4.4.3: Not enough bandwidth for altsetting 0 from the kernel. The device really is detected as UVC, of course: [ 3423.299311] usb 1-3.4.4.3: new high-speed USB device number 12 using xhci_hcd [ 3423.426280] usb 1-3.4.4.3: New USB device found, idVendor=058f, idProduct=5608 [ 3423.426286] usb 1-3.4.4.3: New USB device strings: Mfr=3, Product=1, SerialNumber=0 [ 3423.426290] usb 1-3.4.4.3: Product: USB 2.0 PC Camera [ 3423.426293] usb 1-3.4.4.3: Manufacturer: Alcor Micro, Corp.

Any thoughts? Just to rule out hardware defects I connected it to my windows 7 work machine and it works fine without even installing a driver. I can arrange remote access to the device (maybe as a VM to be able to experiment with the kernel more easily?) if anyone wants it. johannes lsusb: Bus 001 Device 012: ID 058f:5608 Alcor Micro Corp.
