The only way I can think of to isolate the instances is to virtualize them and forward the usb to the VM, there may be another method to do so however.
But that method works, you can even fiddle with the settings (although I haven't done so) and have a 2nd keyboard, but I looked into it once. I have used 3 controllers at once on the same PC though, so that part is fully functional in that method.
