Hi Greg, Thanks for the reply... cat /proc/interrupts is showing interrupts on from usb-ohci and sa1111 (the chip that contains the ohci controller). We're not using an SMP machine. We're using the sa1110 with the sa1111 companion chip from Intel. Does this help clarify the problem?

Does the interrupt count in /proc/interrupts show this? Is this a SMP machine? What chipset? thanks, greg k-h _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: http://lists.sourceforge.net/lists/listinfo/linux-usb-devel
