* We are a "new" style driver with usb_device_id table,

*
* The best interface for us is 7/1/2, because it is compatible
* with a stream of characters. If we find it, we bind to it.
*
* Note that the people from hpoj.sourceforge.net need to be able to
* bind to 7/1/3 (MLC/1284.4), so we provide them ioctls for this purpose.
*
* Failing 7/1/2, we look for 7/1/3, even though it's probably not
* stream-compatible, because this matches the behaviour of the old code.
*
* If nothing else, we bind to 7/1/1 - the unidirectional interface.
