Query: Awesome for PS/2 - USB buyer beware

I got this device and immediately loved it. HOWEVER, I have a USB mouse and I used a USB to PS/2 converter to make it work with this KVM. Over time my USB mouse has stopped working properly and I have to unplug the mouse for several seconds and plug it back in. Otherwise, it does odd things like completely locking up, causing my browser to go backwards and forwards and sometimes closing windows. So, I dug into the documentation and found where it does indeed say that you can't use USB devices with it, which make this purchase was a COMPLETE waste of my money. I suppose it was my fault, but they could have made the USB - PS/2 conversion incompatibility more eye catching. It is very interesting that their USB version of this device is almost twice as expensive.Update: After going through two USB mice, I tried another USB mouse (same type of mouse) and the mouse has been working fine for probably 6 months. So, I'm not sure if it was the mouse or the IOGear device.
