Oh - this is not intended code left over from initial testing.
Can you try this:
--- avision.c (revision 284)
+++ avision.c (working copy)
@@ -5627,8 +5627,7 @@
s->opt[i].unit = SANE_UNIT_NONE;
s->opt[i].size = sizeof (SANE_Word);
- s->opt[i].constraint_type = SANE_CONSTRAINT_RANGE;
- s->opt[i].constraint.range = 0;
+ s->opt[i].constraint_type = SANE_CONSTRAINT_NONE;
s->val[i].w = SANE_FALSE;
}
I can commit this soon if it files your problem and does not cause others
issues during testing on my side.
Yours,

Some expert will probably jump in with a better explanation, but yeah, I read
in one of the man pages that a TV card can interfere. Sane is capable of
treating a TV card as a scanning device (doing frame capture, I presume). If
it picks this card up as the first scanning device, it will be the default.
There's something you need to do to change the default scanning device.
Sorry, I'm not more specific, but I'm a sane-newbie (that is, a newbie to
sane).
