is the CMD/DATA bit. The cmddata method provides selection of command or data.

to call DEV_CONNECT() when they are ready to be enumerated. That is,
(1) initially when bound to the USB driver, and (2) after a USB reset.

Description: USB DMA not fully implemented. Partial logic is in place but it is
fragmentary and bogus. (Leveraged from the lpc214x)
b) Possible errors in USB device driver reported "I suspect there's a few
issues in the lpc214x USB driver -- in particular it doesn't stall both
in/out endpoints for unsupported setup requests and it doesn't call
CLASS_DISCONNCET on a USB reset -- I don't have any access to that hardware
so can't pursue it really."
