Universal Serial Bus Mass Storage Class<br>Bulk-Only Transport<br><br>This specification addresses Bulk-Only Transport, or in other words, transport of command, data, and status<br>occurring solely via Bulk endpoints (not via Interrupt or Control endpoints). This specification only uses the<br>default p
ipe to clear a STALL condition on the Bulk endpoints and to issue class-specific requests as defined<br>below. This specification does not require the use of an Interrupt endpoint.<br>This specification defines support for logical units that share common device characteristics. Although this<br>feature provides the support necessary to allow like mass storage devices to share a common USB interface<br>descriptor, it is not intended to be used to implement interface bridge devices.
