'''Storage Devices'''

'''Ultibo Storage Interface unit'''
  
−
This unit provides both the Storage device interface and the generic USB mass storage driver.
+
This unit provides the generic Storage device interface used by all storage drivers.

'''USB Mass Storage Devices'''
+
−
 
+
−
The USB Mass Storage Class Control/Bulk/Interrupt (CBI) Transport specification is approved for use only with full-speed floppy disk drives. CBI shall not be used in high-speed capable devices, or in devices other than floppy disk drives. CBI shall not be used in devices that implement LSDFS. Usage of CBI for any new design is discouraged.
+
−
 
+
−
Therefore the majority of USB Mass Storage devices use the Bulk only interface.
+
−
 
+
−
USB mass storage class devices normally use the SCSI command set and therefore the USB storage driver consumes the SCSI unit for the protocol and command definitions. USB mass storage devices are registered directly as Storage devices not as SCSI devices.
