Dell Poweredge R210 II not liking Tripplite Ps2 to USB adapter for KVM

system specs

windows server 2008 R2 standard with pack 1

intel xeon cpu 3.10ghz

8g ram

64bit os

named Chaos for good reasons

this server controls our HVAC system for 3 buildings. its all usb which was unknown to me when it was purchased a year ago. on the dell site the district i work for purchased the tripplite ps2 to usb adapter to use with a tripplite kvm. this was done in order to clean up the usb keyboard and mouse that were being plugged into the front of the one u server in the cluster. upon getting this i plugged it in and it seems to find it. however when you try to use the mouse pad the serach window comes up and it goes nonrespnsive. nothing responds at all. i do know it works on 7pro. and yes i did try it on another 08 box, same results.

any ideas?
