7.3.3.6CEh-D2h: Inquiry Product String

BYTE
NUMBER	BYTE NAME	UINT	DESCRIPTION

4:0	INQ_PRD_STR	2640	If bit 4 of the 1st attribute byte is set, the device will
			use these strings in response to a USB inquiry
			command, instead of the USB Descriptor
			Manufacturer and Product ID Strings.

7.3.3.7D3h: Dynamic Number of Luns

BIT
NUMBER	BYTE NAME	UCHAR	DESCRIPTION

7:0	DYN_NUM_LUN	FFh	These bytes are used to specify the number of LUNs
			the device exposes to the host. These bytes are also
			used for icon sharing by assigning more than one
			LUN to a single icon. This is used in applications
			where the device utilizes a combo socket and the
			OEM wishes to have only a single icon displayed for
			one or more interfaces.
			If this field is set to "FF", the program assumes that
			you are using the default value of "04" and will
			display icons for xD, MS, and SD/MMC. If this field
			is any other value besides "FF", you must specify the
			LUN# assignments in the boxes starting with LUN 00
			and going to (# of Icons to Display -1).
			Regardless of this setting, the USB2640/USB2641
			sets this value to ‘1’.

7.3.3.8D4h-D7h: Lun to Device Mapping

BYTE
NUMBER	BYTE NAME	UCHARS	DESCRIPTION

3:0	LUN_DEV_MAP	FFh, FFh, FFh, FFh	These bytes are used to specify the number of LUNs
			the device exposes to the host. These bytes are also
			used for icon sharing by assigning more than one
			LUN to a single icon. This is used in applications
			where the device utilizes a combo socket and the
			OEM wishes to have only a single icon displayed for
			one or more interfaces.
			If this field is set to "FF", the program assumes that
			you are using the default value of "04" and will
			display icons for xD, MS, and SD/MMC. If this field
			is any other value besides "FF", you must specify
			the LUN# assignments in the boxes starting with
			LUN 00 and going to (# of Icons to Display -1).
			Regardless of this setting, the USB2640/USB2641
			sets these values to ‘FFh, 00h, 00h, 00h’.
