I have several boards with PCHs with this chipset in my lab that have no functional USB if XHCI is enabled in BIOS on -CURRENT with all of the currently committed USB changes. Is there anything I can do to help debug this problem? I found PR 179342 but it seems the issues there are resolved -- would going through the debug procedure there be useful?

Hi,

Is the problem fixed if you set:

hw.usb.xhci.xhci_port_route=-1

in /boot/loader.conf

Basically dmesg would do at first.

XHCI is a more high-level controller, and I suspect that the makers have 
added some propritary glue to switch ports back and forth between XHCI 
and EHCI which is not documented anywhere.
