[sane-devel] Epson 2480 Transparency-Adapter?

Tue, 4 Jan 2005 21:27:41 +0100

Hi,
>
> It works out of the box, AFAIK.

at least not for me - maybe I'm wrong at some point?

I didn't work in xsane, nor in kooka, nor with scanimage on the commandline.

>From what I can see in this debug-output, it gets into a countdown waiting or 
the device to get ready, but it gets stuck at 4 seconds until I kill the 
process after some minutes.

Thanks for your Help,
Reinald
