44 / 72 page ![]() USB 2.0 Hi-Speed Hub Controller Datasheet Revision 1.0 (3-11-09) 44 SMSC USB251x DATASHEET 8.2.1.22 Register 15h: Serial String Length 8.2.1.23 Register 16h-53h: Manufacturer String 8.2.1.24 Register 54h-91h: Product String BIT NUMBER BIT NAME DESCRIPTION 7:0 SER_STR_LEN Serial String Length 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.
