stable 5.3 question about KVM connected Mouse?

[David]

Hello,  I was hoping someone in the freebsd community would have the 
answer to this.

 I own a 2 computer connecting Trendnet "TK-209i" KVM swich and have had 
a  problem with it with FreeBSD ever since I owned it.

I can never seem to get my mouse to work when conneceted to my FreeBSD 
machine.

Its an USB 5 button mouse connected to the KVM switch through a PS2 
adapter. It than connects to the FreeBSD machine through a single USB 
connector for both the Keyboard and mouse.

Freebsd 5.3 detects the keyboard fine through the USB connector, but 
"moused" never detects the mouse no matter what port I choose.

I have tried both Windows and Linux with the single USB connector for 
the keyboard and mouse, and they detect the mouse just fine.

My question is what the heck to I have to do to get my mouse detected in 
FreeBSD 5.3 with my current configuration?

I would really appreciate any information people would have on what to try.
