"Text console" is fine.

Okay, you've enabled the generation of debugging output by hkbd(4). What did you do with the generated output? It's the most important piece of information in this situation.

There are three cases here:
  Case A: usbhid is disabled; the keyboard works
  Case B: usbhid is enabled; the keyboard works
  Case C: usbhid is enabled; the keyboard doesn't work

You recently observed Case B. The difference in dmesg between Case B and Case C is what is of interest.

If you start moused, you would get a mouse cursor in the text console. However, with usbhid enabled, the mouse will always not work (the cursor won't move at all) because the current version of moused does not support hms(4) devices. Forget about the mouse for a while.

One extra thing to try is resetting the keyboard with a command such as this:
    usbconfig -d /dev/ugen1.3 reset

If the keyboard doesn't work, the command might make it work. Perhaps the opposite is also possible.
