Hi,

Nothing is seriously broken in the XHCI driver. Try to set:

hw.usb.xhci.xhci_port_route=0

Which will route all devices to the EHCI, in your /boot/loader.conf

Does it make any difference?

Refer to the following print:

The chipset you're using is special in that the binding of ports between 
XHCI and EHCI is not fixed. Maybe some combinations are simply not 
supported.
