Re: [sane-devel] SANE_CAP_ALWAYS_SETTABLE (was Re: Preparing for a sane-backends release)

I removed SANE_CAP_ALWAYS_SETTABLE because it was not in the sane standard, and the only backend that used it set it on every option. As it's intended purpose was not defined by standard, I hoped that it would disappear. If the distros are going to shove it back in, I guess that will never happen.

Cedric- I'm sorry you did not receive a reply earlier, the SANE project is somewhat short handed. In this case, you need to investigate what changed in your system around the time the scanner stopped working. Figure out what packages were updated by the OS, and see if you can downgrade

This is the first I have heard of this scanner, so I doubt it will work with sane currently. There is a good chance that this scanner would use a protocol similar to other Epson-based Fujitsu scanners, which are supported by the epjitsu backend, not the fujitsu backend. Are you able to get a log
