Yes- what we should probably do is add a new set of
sanei_usb_{read,write,etc}_extended() functions, which take the
endpoint as a argument. Then all of the existing functions could
become a wrapper around those, which call a helper function to
determine the 'automatic' endpoint to use.
Thanks for looking into this- I'm not sure if anyone else has had the time....
