USB Auto-detect not working

It would seem the USB Auto-detect on my main Vista Home Premium x64 computer is not working. I try to turn on external USB hard drives, plug in a thumb drive, plug in my MP3 player, I get nothing. They all power up fine (those that run off USB power) but Windows sees nothing. However, if these things are connected when the computer boots, they are recognized and function no problem, but if I disconnect them and try to reconnect, I get nothing again. And to confirm it wasn't just storage devices, I tried my wireless mouse too. It also won't work unless it's connected at boot up. It also does not matter where the device is hooked up. Front USB ports on the case, motherboard USB ports, or back panel USB ports (connected to mobo same way as front ports).

I have been receiving messages saying that a USB device could not be recognized. I figured out that one of the USB ports on the motherboard had stopped working. I disabled the unknown USB device in my device manager and it stopped giving me the message. All was fine for a couple of months. I'm now getting this message again and that's when this crap started. Do you suppose it has something with Auto-detect not working? You suppose the controller is malfunctioning?

Also, one of my externals has eSATA and so does my motherboard. Just to make sure it was only USB, I tested the drive with eSATA and it worked just fine. It was recognized immediately.

BTW, it's an ASUS M2N32-SLI Deluxe Wireless Edition motherboard (Socket AM2 nForce 590 SLI)

Thanks for any help guys.

Well, it started working again out of the blue but no telling how long it'll last. What could cause the Auto-detect to stop working but USB devices connected before hand still function? Do you suppose I should try reinstalling my USB controller drivers?

Ya know what, I'm just gonna assume that the USB controller is messed up. Now the auto-detect is working more or less but when I hook my MP3 player up, I constantly hear the connect and disconnect sounds and then the auto-play menu pops up. It'll happen about 10 times in less than 5 minutes. I hook it up to my laptop, works just fine so it's not the MP3 player.
