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.
