Temporary USB host fix

The close endpoints update broke our ability to open endpoints that
the native TinyUSB driver had already opened. We need to add a way
to fully detach the native driver.

Until then, limit the native HID driver to keyboards only.
CircuitPython uses this for the native keyboard support.
