There is a converter from USB to PS/2 it works with Mouse and Keyboards and doesn't need Drivers.
I have heaps of them. They still come attached to Keyboards and Mouse sold in Australia today. Picture of the Converter here as well, also comes in different colour for Keyboards, each work just as well.
The Package & Installation
The Logitech MouseMan Dual Optical retail box includes the mouse itself, a USB to PS2 converter and driver CD. Installation is very straightforward – simply plug the mouse into the desired interface (USB or PS2) and install MouseWare drivers from the CD. However, keep in mind that many users have reported bugs with Logitech’s software and the mouse is completely operational under Windows native drivers. I guess it all comes down to a matter of personal preference – you can always uninstall MouseWare if it gives you a headache.
Personally, I didn't have much luck with MouseWare. When I first installed it, the mouse pointer would frequently just freeze without warning and I would have to reboot the computer. I checked this with both PS2 and USB, and I tried using MouseWare with and without the weight inside (more on that later). The problem persisted. As a last resort I uninstalled MouseWare and allowed the mouse to run on Windows native drivers. After this, the mouse worked perfectly on both PS2 and USB.

Try asking your friends about them? WIN98SE USB is not really compatible to modern USB, but the adapter certainly works. You could also look for a Mouse made from the people of my Link?
Your Mouse could also be full of gunk? That will certainly do it as well, try disconnecting it from the Computer, turning it over move the retaining plastic for the Ball, it shows you the way by arrows, but be gentle and dont let the Ball drop on the ground? It is probably full of Gunk? To clean it just use a mild detergent and water and let it dry thougherly before inserting it again. Whilst you have that opened look at the two black bars? I bet they are also covereed in Gunk. Use a cotten swab with a few drops of pure Alchol, such as Rubbing Alchol or Metholated Spirits onse again always gently. If you really want to clean out all the gunkin it, just unscrew the single screw and look inside? Clean off the gunk, very gently with a new Cotton Swab and a few drops of alchol and let every thing dry thoughly, even over night, then reassemble your Mouse. I bet it performs better after that.
That always worked for me until I went to Optical Mouse that works on WIN98SE using the adapter and any other Computer that still uses PC/2 connections,easily seen by just looking at the back of any Computer.
