I think I had a similar discussion when we merged the gud driver. gud is 
a driver for a RasPi-based usb display adapter.  My point was that USB 
is just an internal transport bus, like PCI. But that wasn't convincing. 
So now we have USB and other busses as connector types.

My preference would be to use a panel type as Daniel suggested; and 
maybe 'Unknown' for a few special cases.

Best regards
Thomas
