You have it set up correctly.  Well, at least technically correct.  

You cannot use COM2 and COM4 at the same time (as well as COM1 and COM3). 
This limitation should not be a problem, however, since I doubt that you are
modeming around while scanning.  You will not want to use COM3 for anything
since it would conflict with your mouse (trackball).  With that in mind, here
are a few things to try:

	Swap the modem and scanner.  Some software does not support COM3 and 4
	for some stupid reason.

	Take out the modem.  It may improperly handle intterupts.  This is
	more common with older internal modems.

	Take out the mouse (trackball).  Some mice drivers 'latch' onto
	several intterupt lines rather than just the one being used.  (I know
	that 'Trumouse' does this, Logitech does not, others I don't know.)

	If none of these work, keep the original setup (COM1-mouse, COM2-modem,
	COM4-scanner) and reread the manual.  No I am not trying to be a ***.
	Seriously, look for errors in the manual, things you missed the first
	time, or whatever.  Or even the tech support phone number...
