	Hello,

	what values did you provide in gt68xx.conf ? In a recent success report by 
Jarosław Arlet (http://lists.alioth.debian.org/pipermail/sane-devel/2009-
November/025607.html) was using:

usb 0x07b3 0x0454
vendor "Plustek"
model "OpticSlim 2400+"
firmware "/usr/share/sane/gt68xx/cis3R5B1.fw"
override "plustek-opticslim-2400"

	What you see might be due to overriding with an inappropriate model.

Regards,
	Stef
