Need help with new 5-button mouse

[John Foster <jfoster@augustmail.com>]

I just installed a new 5-button Fellowes mouse;  4-buttons & a scrolling 
wheel. I have tried the autops2 setting   & the right, left, & wheel(button) 
function work but the scrolling function does not. I also tried the fups2, & 
brw drivers  whith similar results. I have the mouse connected through a ps2 
port using a usb adapter.
1. Is there a possibility that the native usb driver will work properly? It is 
installed but I never used it. I would have to buy an extension cord for 
that.
2. Any one else have this type of mouse working.
3. Any ideas or suggestions.
Thanks!
