[sane-devel] Plustek OpticSlim 2400 problem

[Eggert Ehmke (FTV)]

Hello,

I try to install a Plustek OpticSlim 2400+ scanner at a ADM64 Gentoo Linux 
system. 

$ scanimage -L
device `gt68xx:libusb:001:007' is a Plustek OpticSlim 2400 flatbed scanner
However, 
$ sane-find-scanner -q
found USB scanner (vendor=0x07b3, product=0x0454 [Genius CP-Slim 1200], 
chip=GT-6816) at libusb:001:007
When I scan some images using xsane or via scanimage, the result is a random 
gray pixel image. These are the outputs of the command:

$ scanimage -v --device-name gt68xx:libusb:001:007 --resolution 300 --format 
tiff > image.tiff
