[sane-devel] fujitsu illegal request: invalid field in parm list

[Tim McGuire]

In reading the recent messages I've seen a couple of cases with Fujitsu backend like (http://lists.alioth.debian.org/pipermail/sane-devel/2007-April/018982.html) 
and 
(http://article.gmane.org/gmane.comp.graphics.scanning.sane.devel/10792)
where ..

well, sorry to dump more on, but me too.  This is happening with every combination of parameters I try
I've got a fi-5750C (with USB) Suse 10.2
I'm using fujitsu backend 1.0.33 as you can see and I see there is a newer one (1.0.47) in CVS, but that the most recent poster has similar issue with the 1.0.47.

I'd like to know if there are some arguments from the command line I can fiddle with to make the scanner happy?  Or, some other remediation.  Would it be worth it to grab the 1.0.47 version? Would it be worth it to try the SCSI?

thanks for all your hard work on this stuff,

Tim
