However, the external EEPROM might be nice: Otherwise your device will show up as 'generic USB hub' on the PC. Alternatively, you could probably emulate an EEPROM with your onboard microcontroller (configure one of the I2C interfaces to act as a slave). Then you could report it as a 'Speaker system driver and codec controller' or something like that. | |
