The SCSI family of standards provides for different transport protocols that define the methods for exchanging information between SCSI devices. This standard defines the methods for exchanging information between SCSI devices using a USB interconnect. Other SCSI transport protocol standards define the methods for exchanging information between SCSI devices using other interconnects.

This standard describes a SCSI transport protocol (see SAM-4) for USB-2 and USB-3 with the following properties:

a) mechanism to send commands associated with any T10 command standard to a USB device;

b) complies with SCSI Architecture Model - 4 (e.g., autosense and command queuing); and

c) other capabilities.
