Now the scanner itself could be somehow a bit damaged but I think this is unlikely.
Yes, also given that it works fine with another desktop, that seems unlikely.
For now it is only a gut feeling but I think that something goes wrong during USB data transfer in the software that is used for the low-level USB data transfer.
I have been thinking exactly that.
For me it looks as if while the data is being read from the scanner, the data becomes more and more distorted and this seems to indicate that something goes more and more wrong during USB data transfer.
One little hardware difference - office11, where the scanner works, has a local disk as root, office12 and -13 both boot from NFS. It seems like a long shot, but the two NFS-root machines probably have more I/O and interrupts happening during the data transfer. I might try another machine with local disk and see what happens.
Please install kernel-default and boot with it (you may have to manually select it in the Grub boot menue) and then run
# lspci -v | egrep -i 'usb|hci'
# lsmod | egrep 'usb|hci'
and post the output of both commands here.
Willdo. -- You are receiving this mail because: You are on the CC list for the bug.
