Controller unplug/replug is unresponsive

[hawsman2]

I have an admittedly glitchy Xbox 360 PC controller. The wires are a little shot and every once in a while the power will blip on it for a microsecond. So the computer registers it like it disconnects and then reconnects. Problem is that these, even when it's back up and reconnected, even after reloading the game i was playing, the emulator will not respond to it. Is there a way to work around this? Alt-F5'ing does not work.
