Have a question about the functionality of sane_open vs sanei_usb_open 
(and other parallel functions). As I understand it, sanei_usb_open opens 
up a connection to send and receive usb specific information.  What I'm 
confused about is if there is any overlap with operation sane_open. Could 
someone highlight the difference of the two for me. In 
the same spirit are sanei_usb_read_bulk and sane_read mutually exclusive 
in the function they perform? is there any over lap? what's the explicit 
purpose for each one? what can each do that the other can't?
