Hi, as I said in my last post, I am writing a backend for Hercules Scan at home 48 USB scanner. This device uses an unusual USB interface which has 3 bulk endpoints: * EP 0x01 is used to send commands to device * EP 0x82 is used to get the result of some commands * EP 0x83 is used to get scan data In its current state however, sanei_usb API does not allow us to choose what endpoint to use for bulk transfers. It will always use the first IN and OUT endpoints it finds for functions sanei_usb_read_bulk() ans sanei_usb_write_bulk() respectively.
To overcome that limitation, I thought of adding a few functions to sanei_usb API to allow specifying an alternative endpoint (for instance: sanei_usb_read_bulk_ep() which would take an additional ep argument of type SANE_Byte). It wouldn't break any existing backend. Would a change of that kind be accepted ? Or should I use libusb directly ? Thanks in advance. --- Hugo Grostabussiat
