Supported UNICODE Language Table:
This table is used as the "string" of index 0, which is defined in the USB-Standard. This "string" is actually a list of all
the LANGIDs that are supported by the device. The first two bytes in this table are needed for the standard format of
USB String descriptors.

Table Of Descriptor Pointers
This table is used by the ZR36504 to locate the start address of a given descriptor. Each item in this table consists of a
Descriptor Identifier byte (first byte), and EEPROM address (second byte - contains only 8 most significant bits of
address; the other 3 bits always equal '000').
