Hi, Thanks for not giving up on it. 1) system with working scanner: Laptop HP625 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.
