Hi, Thanks for not giving up on it.
1) system with working scanner:
Kernel 2.6.38-15-generic-pae #61-Ubuntu 32 bit
libusb-0.1-4 version 2:0.1.12-17
libusb-1.0-0 version 2:1.0.8-2
2) system where light doesn't turn on:
Abit Mainboard with AMD64X2 5600+
Kernel 3.2.0-25-generic #40-Ubuntu 32 bit
libusb-0.1-4 version 2:0.1.12-20
libusb-1.0-0 version 2:1.0.9-rc3-2ubuntu1
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.
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.
I found nothing relevant to USB in the BIOS, so I haven't tried anything
in this direction.
There is no message being logged when the light doesn't turn on.
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.
Best greetings from Luxembourg
