Can I use the default VID/PID and default descriptors to avoid the need for an external EEPROM ?

Question: Can I use the default VID/PID and default descriptors to avoid the need for an external EEPROM ?

 

Answer:

You do not need an external EEPROM for the hub to operate. The hub will enumerate with the default VID/PID of 0x04B4/0x6560. This configuration can be used for test/development purposes.

However, for production, you will need your own VID/PID in order to pass USB compliance and get the hub certified. You can configure the hub to use your VID/PID in one of two ways:

  1.   Add an external EEPROM to your design. The external EEPROM will be programmed to provide your VID/PID, descriptors and other hub configuration settings.
  2.   Purchase your parts with the internal fuse links set to your VID/PID (this is a factory function only and cannot be done after packaging).

Please see the datasheet for more information.
