Description

Ultibo SCSI Interface unit

The SCSI interface unit is device non specific in that it implements only the SCSI protocol.

Actual command transfer is performed by a device specific driver that implements the exact semantics of the device. eg USB Mass Storage devices use the SCSI protocol, the SCSI interface implements the protocol behaviour but the actual command transfer is handled by the USB storage driver.
