   2           A Simple bulk IN transfer.  Loads EP2IN buffer with an incrementing count, 
   3           then arms IN2 for transfer.  When transmitted, replace byte zero of the 
   4           EP2IN buffer with a count indicating the number of IN transfers and re-arm
   5           EP2IN for the next IN transfer.
