Hmm, you do not set USB configurations. I know this might
be good for Linux but this will not work under Windows.
Not so sure about FreeBSD.

I have tested some codes under Linux/Windows and
I will do the tests for FreeBSD. I already tested pk2
and Piklab for PICkit 2 under FreeBSD with the help
from people here. I always set configurations and
calim interfaces (interrupt transfer for PICKit 2 -- HID device).

Not so sure about control transfer. I think you do not
need to claim the interface.
