[sane-devel] Network connected scanner, i/o error if scanner is idle for longer then 40sec

[Paul Newall]

I found, using the kodakaio backend, that leaving the scanner idle 
between scans for more than around 40sec gives an i/o error when I try 
to scan again.
I can scan any number of times with gaps of less than 30 sec between 
scans without getting this error.

Has anyone ever had a similar experience with any other backend?

Does anyone have an idea what might be the cause?
