This is a very unfortunate and annoying problem on Linux.
Fortunately, this problem will be fixed once Linux v2.2 is out (which
will have support for /proc/sys/kernel/sg-big-buff). In the meantime,
always make sure the SG_BIG_BUFF in SANE matches the one used by the
kernel.

GIMP queries a plug-in only when it looks like it's something new.
What you might want to do is:
(a) make sure all your scanners are turned on
(b) "touch" the xscanimage binary
(c) start gimp
This way, GIMP should re-query xscanimage and then it should be able
to find your scanner (the three steps need to be redone each time
there is a change in the device configuration).
