For FatDog you need 3 64-bit packages:
For Puppy you need 3 32-bit packages:
Step 2: In a terminal, execute the following command:
iscan-registry -a interpreter usb 0x04b8 0x0131 /usr/lib/esci/libesci-interpreter-gt-f720
Step 3: Edit the /etc/sane.d/dll.conf file.
You want to comment out all the scanners that you are not using and add the word "epkowa" at the end of the file.
(Note that I also commented out the Epson & Epson2 scanners ... epkowa was the only scanner I listed in the dll.conf file)
That's all there is to it.
I tried this out on 64-bit Fatdog (500 & 600).
I also tried it out on Puppy-511, Slacko-5.4, & Precise-5.4
Note that step #2 is usually what gets missed. This command puts a file called "interpreter" in /var/lib/iscan ... This file should have a single line in it for your scanner. In this particular case, the vendor and model IDs are for the Epson V300 scanner ... if you have a different model scannner, you would need to run "lsusb" in a terminal to determine the IDs to use in step 2.
