Thanks, on the 2480 this was really the case. On the 2580 it was already 
open.

Now I have tried to scan with the 2480 and I was even successful 
sometimes. When it worked the problem was that there were long delays 
until the scan to start (command line) or the GUI to appear (xsane). 
There were console messages like

-----------------------------------------------------------------------
[snapscan] Scanner warming up - waiting 9 seconds.
[snapscan] Scanner warming up - waiting 33 seconds.
[snapscan] Scanner warming up - waiting 9 seconds.
[snapscan] Scanner warming up - waiting 33 seconds.
-----------------------------------------------------------------------

-----------------------------------------------------------------------
scanimage --test
-----------------------------------------------------------------------

worked with the long delays before actual scanning as described above.

-----------------------------------------------------------------------
SANE_DEBUG_SNAPSCAN=255 scanimage > 1.pnm 2> eps2480_2debug.log
-----------------------------------------------------------------------

produced a correct output. 1.pnm was a scan of the full scanning area. 
Again the long delays.

-----------------------------------------------------------------------
SANE_DEBUG_SNAPSCAN=255 xsane > eps2480_3debug.log 2>&1 &
-----------------------------------------------------------------------

Successful run of xsane. Nothing than one pre-scan of the full scanning 
area was done. In another run of xsane the GUI opened but pre-scanning 
did not work, real scanning worked then and pre-scanning only bafter the 
first real scan.

On all later attempts I got a segmentation fault when the GUI started to 
open. The command line was the following:

-----------------------------------------------------------------------
SANE_DEBUG_SNAPSCAN=255 xsane > eps2480_4debug.log 2>&1 &
-----------------------------------------------------------------------
