Product ID
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 Mass Storage Class Bulk-Only
Transport Specification requires a unique serial number (in
upper case, hexadecimal characters) for each device.
Number of configurations supported
1 for mass storage: 2 for HID: 3 for CSM

Length of configuration descriptor in bytes
Descriptor type
Number of bytes returned in this configuration. This includes
the configuration descriptor plus all the interface and
endpoint descriptors.
Number of interfaces supported
The value to use as an argument to Set Configuration to
select the configuration. This value must be set to 0x01.
