Thanks for not giving up on it. <br>
<br>
1) system with working scanner: <br>
Laptop HP625 <br>
Kernel 2.6.38-15-generic-pae #61-Ubuntu 32 bit <br>
libusb-0.1-4 version 2:0.1.12-17 <br>
libusb-1.0-0 version 2:1.0.8-2 <br>
<br>
2) system where light doesn't turn on: <br>
Abit Mainboard with AMD64X2 5600+ <br>
Kernel 3.2.0-25-generic #40-Ubuntu 32 bit <br>
libusb-0.1-4 version 2:0.1.12-20 <br>
libusb-1.0-0 version 2:1.0.9-rc3-2ubuntu1 <br>
<br>
The problem occured also when both machines where running Ubuntu
11.04 with the same kernel version except the one on the desktop
was 64 bit. <br>
<br>
Another hint: On the desktop running the scanner inside
VirtualBox with Windows XP and the linux kernel 1) above as the
host OS it doesn't work for now. Although I recall that it
worked once. The kernel versions are changing rather often
nowadays along with the updates. <br>
<br>
I found nothing relevant to USB in the BIOS, so I haven't tried
anything in this direction. <br>
<br>
There is no message being logged when the light doesn't turn on.
<br>
<br>
In the past I compiled some kernels from source, maybe I should
try to revert to an older kernel for testing. I'm not sure if
I'm able to get it to work though. Grub has got so complicated
and I'm not sure if I run into problems with the versions of
libc and so on. <br>
<br>
Best greetings from Luxembourg <br>

Hello,<br>
<br>
thanks for all these data. I have uploaded at <a
moz-do-not-send="true" class="underline"
href="http://dl.free.fr/gEzUYJkHX"
onclick="window.open('http://dl.free.fr/gEzUYJkHX'); return
false;">http://dl.free.fr/gEzUYJkHX</a> 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.<br>
<br>
Regards,<br>
Stef<br>

Hi Stef,<br>
<br>
I tried it on the desktop computer. The lamp doesn't turn on, but
otherwise the program functions normally and a black image of
1292x150 pixels is written.<br>
<br>
Greetings<br>
