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.

If you are using iscan you can handle the button (in Xsane it doesn't work)

You will need arguments in scanimage, scanadf etc - else the GT-2500 will
work in flatbed mode.

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:
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.
