Jupp - There is a check missing :-(.

Great that it works. Can you send a patch or explain exactly what you did.

Please try to find out some more. I don't have a 600 so I cannot do it myself.

A Multiplexing would be needed. Maybe the parport driver in the linux kernel
can handle this. I've not tried it yet.

Yes it is. Simply use saned. This way you can also use the scanner as
non-root.

It uses the calibration data. It's stored in "/tmp/.primax.calib".
You can dump debug strings via printf. Use XSane with root permissions.

Would be great if we could make the D600 work.
