Hi Frank, Does your device actually expose both isoc and bulk endpoints? If I recall from the datasheet, whether isoc or bulk mode is provided is not actually configurable from the driver. The EEPROM dictates how the endpoint map gets defined, and hence it's either one or the other. If that is indeed the case, then we don't need a modprobe option at all (since would never actually be user configurable), and we should just add a field to the board definition to indicate that bulk should be used for that product.
