I just discovered something:

drvctl -l -t

gives a list of devices in tree format.  Here is the relevant part.

    xhci0
      usb0
        uhub0
      usb1
        uhub1
          uhub2
            uhidev0
              ukbd0
                wskbd1
            uhidev1
              ums0
                wsmouse0
              uhid0
              uhid1
              uhid2
            uhidev2
              uhid3
              uhid4
              uhid5
              uhid6
            umass1
              scsibus1
                sd1
          uvideo0
            video0
          uaudio0
            audio1
              spkr2
          umass0
            scsibus0
              sd0


It is USB-3.0 . I thought I should mention that I tried this on
Windows 10.x . It works fine.
I got it for 2 USD, so I decided to test it first.

I compiled NetBSD-9-HEAD. It choked at the sat step where it stripped
stuff. Can I run
NetBSD-9-HEAD on a NetBSD-9.2 system?
