8.4.3

Device ID Strings

 

These bytes are used to specify the LUN descriptor returned by the device. These bytes are used in

 

combination with the device to LUN mapping bytes in applications where the OEM wishes to reorder

 

and rename the LUNs. If multiple devices are mapped to the same LUN (a COMBO LUN), then the

 

CLUN#_ID_STR will be used to name the COMBO LUN instead of the individual device strings. When

 

applicable, the "SM" value will be overridden with xD once an xD-Picture Card has been identified.
