Hello Hans, thanks for your reply. I've connected only the webcam, no other devices. I've tried to connect via un USB HUB but the result is always the same: Aug 14 15:56:50 cchi-desktop kernel: [ 8434.924045] gspca: usb_submit_urb [0] err -28 This web-cam is never worked using Linux, but it is reported full working.
