It looks like you have a PCI interrupt routing problem. I'd look at how the OHCI controller is hooked up to your PCI bus. Since you mentioned that the OHCI controller is connected to IRQ5, yet /proc/interrupts shows it connected to 10, I think something is not working properly :) Good luck, greg k-h _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-users
