When supported, the maximum string length is 31 characters.
BIT
NUMBER BIT NAME DESCRIPTION
7:0 MFR_STR Manufacturer String, UNICODE UTF-16LE per USB 2.0 specification
When supported, the maximum string length is 31 characters (62 bytes).
Note: The string consists of individual 16-bit UNICODE UTF-16LE
characters. The Characters will be stored starting with the LSB at
the least significant address and the MSB at the next 8-bit location
(subsequent characters must be stored in sequential contiguous
address in the same LSB, MSB manner). Some EEPROM
programmers may transpose the MSB and LSB, thus reversing the
Byte order. Please pay careful attention to the Byte ordering or
your selected programming tools.
