Hi,
There is no issue with suspend as I'm aware.
The problem is resume, that we would like to completely reset the HC and
re-start enumeration and not use the handover from the BIOS.
You should also check what the BIOS is doing when it sees a HC which is
different modes when entering suspend.
USB code is here: sys/dev/usb/controller/{ehci.c,uhci.c,ohci.c,xhci.c}
