[sane-devel] plustek backend failing to open device under non-root

Well, the USB IDs are there in plustek.c :), 
and, in fact, I've successfully used this same 
box+scanner back in 2010 (such hardware lifespan 
must be a thing unheard of in the West :) More, 
I've did it as a normal user then, so I know 
it's possible.

The point is the software actually somehow fails 
to open a lock file in /var/lock/sane, which 
must involve some subtlety in my system. Like, 
why does the device node get its group owner set 
to 'lp'?

Will have to try with new dailies, but what 
about that alleged recent plustek backend
