Thanks for not giving up on it.

<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

Hello,<br>
<a class="underline" href="http://dl.free.fr/gEzUYJkHX"
onclick="window.open('http://dl.free.fr/gEzUYJkHX'); return

thanks for all these data. I have uploaded at <a
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>
