Device release number in BCD LSB (product release
number).
Device release number in BCD MSB (silicon release
number).
Index to manufacturer string. This entry must equal half of the
address value where the string starts or 0x00 if the string does
not exist.
Index to product string. This entry must equal half of the
address value where the string starts or 0x00 if the string does
not exist.
Index to serial number string. This entry must equal half of
the address value where the string starts or 0x00 if the string
does not exist. The USB
