[sane-devel] using Epson 2480 Photo with sane

[Gert Ahrens]

Hi,

I found in the archives from October connecting details for the Epson 2480 
Photo scanner. I compiled all packages sane-backends-1.0.15, 
sane-frontends-1.0.13 and xsane-0.96 on an AMD x86_64 system without any 
problems.
One time I tried to use my scanner I had success and all stuff was functional.
Each time later I had only the below output from xsane. I tried to use the 
firmware file from my installation disk and later l loaded the software from 
the epson us-site and used that Esfw41.bin without changes. Folks I get 
crazy.
Why only one time?

Thanks for your support
Gert

Thats to output of the xsane-command.
