Not recognizing USB devices

[lt.murda]

Ok well here's the deal.Lastnight my USb was acting funny and today its not working.The only thing its recognizing ATM is my keyboard and mouse.When I plug my PS2 controller or my mp3 player up it doesnt recoginize them.It says unknown USB device.Ive tried everything I could think of.I even reinstalled chipset drivers and went into bios and made sure everything concerning usb functionality was on.Im stumped.Any input?

Have you tried uninstalling the USB root hubs in device manager and then letting Windows find them again? That may clear up your problem.

Tried.Didnt work.I also noticed that I have to plug my Keyboard/mouse into a certain port,or else it says usb receiver has had problems installing.I'm guessing thats my wireless mouse receiver seeing as how my mouse doesn't work when it says that.
