the list of available resolutions gets reported by the scanner. So if  
see resolutions up to 3200 dpi, the scanner can actually support all
of them.

Your kernel is relatively old, and the timeout problem is a known  
problem -
even though it's more likely to occur when you can using a transparency

If you cannot update your kernel, you can modify a timeout value in
the scanner.c source file. Which kernel version are you using exactly?
With this information I may be able to tell you which line to change.
