adding support for nikon super coolscan 5000 ED
I try to use my Nikon Super Coolscan 5000 ED with the coolscan2/coolscan3 backend. I try to scan wit the MA-21 slide mount adapter. Everytime I try to "Acquire Preview" or "Scan" I get a error message:
Failed to start scanner: Document feeder out of documents.
If I use the SA-21 strip film adapter the scanner tries to feed the film in, but stops during the process and I get the error message:
Failed to start scanner: Error during device I/O.
I use started the xsane with the following command:
xsane 'coolscan3:usb:libusb:002:018' and I used LANG=C to remove local translations of the error messages.
I have some knowledge about C, but nearly no knowledge about the SANE internals nor about USB stuff. If somebody can give me some hints, how to solve this issue, I can try to help to fix it.
