Whatever SuperSpeed device I plug into USB-C port it gets recognized as
HighSpeed only.

"cannot reset port 1!?" message appears on almost (3/4) each 'usb start'
and each 'usb reset' command.

Also checked one of those usb-c 2 usb-a/hdmi/usb-c-charge dongles and
Sandisk was recognized as HighSpeed.
