'Healing' troubled scanner <-> Linux cooperation

My Epson scanner has worked like champ together with linux for over ten years but I have experienced problems recently and since the cure I found elswere was not to be found in BL's forum I create this post.

Symptoms: Out of the blue applications such as Gimp and gscan2pdf could not find the scanner. I had changed nothing as far as I know and all checks (dmesg etc) came up with the correct answers and all the correct sane components and epson scanner drivers were still installed.

Finally I found the following cure somewhere over in the Ubuntu part of internet.

There are configurations files for the scanner drivers and sometimes they need to be edited to help the driver/sane. It should not be like this but sometimes yu have to do it anyway. Since I have an Epson scanner the files of interest are /etc/sane.d/epson.conf or/etc/sane.d/epson2.conf depending which of the drivers that is used.

Run

sane-find-scanner

to get the codes for device and vendor. If this command does not come up with this information you have a more serious problem at hand.

The you edit the line in the .conf file that starts with

usb

You simply add the codes sane-find-scanner found for you. In my case the result looks like this:

usb 0x04b8 0x011b

Edit:
I spoke too early. After posting this I thought I'd better do another test-run. I did and it does not work any longer. All files mentioned above still look OK and still it does not work -- it worked two days ago. I am completely stumped! Anoyingly, xsane enters an un-killable state and if I change something and want to do another test-run I must re-boot first.
