Query: Never ending grief

I've had this product for 2 years, there has never been any FW updates. It will work for a bit, then mouse will mess up. buttons, scroll wheel, left and right button signals get mixed. Some times powering down all devices(pain) and unplugging the power to the kvm will fix it, but not always. Extended function for you mouse will not work so forget the joys of that. Support is as bad as it could get, if you have a weak heart just put it in the trash and save yourself.
