     thanks for all these data. I have uploaded at 
http://dl.free.fr/gEzUYJkHX a small 'gl124' unit test program. It does 
an uncorrected color scan at 150 dpi. It is a fully static 32 binary 
using libusb-1.0.9 . Put it in a directory, copy your genesys.conf file 
in the same directory then run it. You should see the lamp switch on. 
I'm curious to know how it behaves in the "buggy" hardware combination.
