Scanner Install ? Mustek 600 CP

Does anyone have any experience installing a Mustek 600 CP scanner ? I have hooked up the scanner to the computer (P3 /Win 98se) via port to port cable.(non USB). I have installed the software. But the computer does not seem to know the scanner is part of the system? Also there is no scanner icon on the desktop . I got this scanner 2nd hand without any paperwork installation procedures . Any advice, suggestions welcome .
