Hi,
The port speed is decided by the hardware after port reset.
Setting "sysctl hw.usb.uhub.debug=15" should reveal some more
information about the port reset sequence.
Please also ensure you are running 9/10-stable when testing, hence there
are some minor fixes for XHCI every now and then.
Try to collect some more logs from UHUB driver first. Compare bad and
good case.
