There is not much change between pre3 and pre4. The only change that
might influence the detection of your scanner is the "endpoint detection
cleanup". See http://www.meier-geinitz.de/kernel/ for which patch went
in which version. But I would be surprised if this is a problem.
I keep 2.4-latest and 2.5-latest as similar as possible. The
differences are related to API changes and new features in 2.5.

Well, then I guess it's something else (not related to the kernel
scanner driver). Please enable SANE_DEBUG_SANEI_USB=255 also.

What kind of device is the first one?

If my xserver ran on 2.5, I would use it also for the development
