[sane-devel] usb_claim_interface() missing?

[Beat Birkhofer]

Hi

The libusb-documentation states that usb_claim_interface() (and thus 
usb_release_interface()) must be called when performing any 
operations related to his interface (usb_bulk_write() etc.).

In sanei_usb.c usb_claim_interface() is only called in usb_open(). I 
get somewhat further if I pad usb_bulk_write() and usb_bulk_read() 
with usb_claim_interface()/usb_release_interface().

Regards
