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.
