I have a big problem with my USB ports. I uninstalled USB drivers and devices in device manager after following instructions from a an article on Microsoft's site. Now the keyboard and mouse don't work and I can't do anything. The USB ports work fine in BIOS. They *don't* work in safe mode, and they *don't* work after selecting "repair my computer" or whatever it's called. I've been searching the internet extensively and found no satisfying solutions. In fact I'm becoming really nervous that I messed something up for good after reading somewhere that deleting the host controllers makes the USB ports unrecognized by the motherboard. I have a single PS2 slot and will buy a mouse tomorrow, but I still don't know what I have to do to fix the USB problem even if that mouse works?

Any idea?

Please help.
Thanks!

I didn't find the right solution from the Internet.
