Hrmn, uvideo selects the same endpoint / format / whatever each time - anyone know if uvideo makes any decisions based on the bus speed? One thing to try with ehci, is to remove the patch I attached before, then on the line: + (trans_count % 64 == 0 && trans_count != 0)) Change 64 to 16, and apply again. I've still little idea whats causing this fault, reducing the amount of data sent between interrupts might make a difference. On Mon, Oct 27, 2008 at 1:57 AM, Martin S.
