The changes include:

* Setting of USB SPI limits based on the device's USB protocol

* Creation of context states to keep track of bytes written to
  and read from the device and individual USB packets.

* Creation of helper functions for handling transfer of data
  between the USB packets and the data buffers.

* Removal of magic numbers on the USB return codes. Some renaming
  of to make the protocol version clear.
