[sane-devel] xsane - DOES NOT save file preference on exit

[Joseph]

I have two scanners:
- Epson Perfection
- Fujitsu ScanSnap S1500

In both scanners there is box checked in preference: "Save device preferences at exit"
This works on Epson scanner, for example if I change the resolution it saves the setting to my home directory .sane/xsane/file_name.drc

But it does not work on Fujitsu ScanSnap, it reverses the scan resolution to "50" instead of my setting "150dpi"
Why such a strange behavior? What is controlling it?

File in directory ~/.sane/xsane have correct permission:
-rw-rw---- 1 joseph joseph 1837 Dec 7 13:00 Epson:GT-9300.drc
-rw-rw---- 1 joseph joseph 1877 Dec 7 13:27 FUJITSU:ScanSnapS1500.drc

I've tried to change setting in the text file: FUJITSU:ScanSnapS1500.drc
"resolution"
150
"y-resolution"
150

but the changes reverse back to :
"resolution"
50
"y-resolution"
50
