device returned in 1000 byte per second units.
Continuous Transfer Limit: This field indicates the number of blocks (of the current
block size) that can be transferred without delay due to a buffer limitation. When
DISCONNECT is set to 0, transfers restricted to the Continuous Transfer Limit will
result in efficient use of the bus. When DISCONNECT is set to 1, this field is ignored.
