Well "variant"? It does use the Avision driver ... It basically just 
injects the proper ID ;-)

The bulk status read is implemented the right way (tm) in the backend in 
the meantime:

   http://svn.exactcode.de/sane-avision/trunk/backend/

Just place those files in your sane-backend-1.0.15/backend directory and 
recompile. (I just added the ID, so just try to run it without any edit)

Please report success. And if error happens provide the log of:

SANE_DEBUG_AVISION=7 program 2> minolta.log

Where program can be anything you prefer like scaniamge, xscanimage, ...

You do not need much time, as long as you can provide some DEBUG_... 
logs we should get it working quite soon.

If bigger problems arise this might come handy. So far trying the latest 
backend version from my Subversion repository is enough.

Btw. There is a dedicated SANE/Avision homepage:

   http://www.exactcode.de/oss/avision/

And since yesterday a dedicated mailing list:

   http://www.exactcode.de/oss/avision/feedback.html

PS: Please always CC the backend author, mails to the list might be 
overlooked during high workload ...

Sincerely yours,
