That kind of behaviour can be caused by a USB core bug (quite unlikely though), a camera firmware bug that makes the camera crash and reboot (much more likely) or by electrical issues such as bad cables or a noisy environment (both are usually related). If you have a Windows partition on the computer, does the camera work on Windows ? Can you also try a Ubuntu 10.04 live CD ? -- Regards, Laurent Pinchart _______________________________________________ Linux-uvc-devel mailing list Linux-uvc-devel@lists.berlios.de https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
