\r
  Defination for the USB mass storage class driver. The USB mass storage\r
  class is specified in two layers: the bottom layer is the transportation\r
  protocol. The top layer is the command set. The transportation layer\r
  provides the transportation of the command, data and result. The command\r
  set defines what the command, data and result. The Bulk-Only-Transport and\r
  Control/Bulk/Interrupt transport are two transportation protocol. USB mass\r
  storage class adopts various industrial standard as its command set.\r
