I wouldn't be surprised, a lot of usb stuff has been walked around in 
and had its tires kicked between 2.4 and 2.6.  Later!  See below, its 
fixed and working.

I now note that if set from the same cli rather than "export"ed to the 
env, it actually does work.  That surprised me, but really, after 69 
years, nothing should anymore. :)

Its commented out in /usr/local/etc/sane.d/dll.conf.

Now it gets weirder, both of the above lines result in a functioning 
scanner!  xscanimage makes me select the plustek driver as usual, and 
then it runs the scanner just fine.  xsane, from an icon, always says 
the scanner is busy, and its the xsane interface I'm used to.  More 
eye candy I guess.

Hmmm, I just found, dated aug 1 2003, an /etc/sane.d directory, with a 
dll.conf in it.  I had deleted that months ago!  So 
/usr/src/xsane-0.90 just got its config.cache rm'd, and its in the 
rebuild process right now after issueing a ./configure 

And that was it, its now working normally, so one more problem is 
solved.  Many Thanks for pointing me in the right direction (again).

Damn, I find it harder and harder to see the tree for all that forest 
as the years pile up.  I don't recommend getting old, it gets 
embarrasing at times. :(

Now, if I could get the latest epkowa driver to compile & work, it in 
older versions, doesn't have that image artifact the plustek driver 
shows, and which I've sent smallish clips of on a couple of
