Not sure about debugging the xhci driver, but if you compile out the xhci driver from your kernel, and then after the APU2 has booted load it (or leave it unloaded) does the USB device behave as expected on its normal external ports ? I had to do this on an older version of the board to work around some timing issues. ---Mike -- ------------------- Mike Tancsa, tel +1 519 651 3400 x203 Sentex Communications, mike@sentex.net Providing Internet services since 1994 www.sentex.net Cambridge, Ontario Canada
