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. 8.4.3.1 AAh-B0h: Device 0 Identifier String 8.4.3.2 B1h-B7h: Device 1 Identifier String 8.4.3.3 B8h-BEh: Device 2 Identifier String 8.4.3.4 BFh-C5h: Device 3 Identifier String 8.4.3.5 C6h-CDh: Inquiry Vendor String 8.4.3.6 CEh-D2h: Inquiry Product String BYTE NAME DESCRIPTION 6:0 DEV0_ID_STR Not applicable.
