Can't confirm this - with me, using the iscan gui, preview starts almost immediately. However if you are in a network and saned is running it may take some time till saned has identified all available scanners and is presenting a selection list. > it's a very long time!

You will need arguments in scanimage, scanadf etc - else the GT-2500 will work in flatbed mode. > > 4- For these "high speed" scanners is USB 2.0 necessary in order to get > the maximum performance? Or USB 1.1 is enough? No idea, I have only USB 2.0. Note, to run the GT-2500 you will need the epkowa backend. It isn't part of the SANE drivers, but it perfectly fits in. You can get it here: http://avasys.jp/eng/linux_driver/ In summary I would say the GT-2500 is a very recommendable machine, especially with heavy duty jobs when hundreds of sheets have to be scanned in one swoop.
