Hi, I'm helping out a friend with her computer, but I've never run into this problem before. Her computer has all the updated drivers (I put them on myself to make sure), the BIOS is correct, the microsoft updates are installed and everything is as it should be. However, no USB device works, and neither to the CD/DVD Roms work. I can't use a flash drive, or use a USB keyboard/mouse or printer. I don't understand why this is happening. I've already uninstalled the USB controllers and then let the system re-find them, but that still doesn't work. I've run the anti-virus, anti-spyware, etc. Any suggestions?

is this a fresh install? Are there yellow ! marks in the device manager? You may have to install the chipset drivers from the HP site. If that doesn't work, try a repair install as that should load in the drivers. As a last resort, you may have to do a complete reformat and fresh install. Good luck Some HELP in posting on Computing.net plus free progs and instructions Cheers

No, this is not a new install, there are no yellow exclamation points, and my drivers are all updated (as previously stated). I repaired the Operating System, and guess what? It destroyed all my work of updating the drivers and now I'm back to square 1. I don't want to do a fresh install because I'm not convinced that it would fix it, since the repair made it worse, and 2, its not my computer, I don't want to destroy the contents. Thanks anyway.

did you do this repair install? http://www.microsoft.com/windowsxp/... I can't see a repair install making it worse as it would reload everything that was missing or corrupt. What errors do you get when trying usb devices? Some HELP in posting on Computing.net plus free progs and instructions Cheers

Yes, that's exactly what I did. It certainly did make it worse. When I ran DriverMax, all the Drivers that I installed (24 out o 26) reverted back to their previous versions and I had to re-install them. I already install the chipset from Intel's website and I still don't have USB. This is very frustrating....I seriously have never had this problem before..... :(

drivermax? Hmmmm....I think we are on a different page here, EDIT: sorry, never heard of it but I just googled it, looks interesting so I'll try it....thanks for the tip. What ERROR messages are you getting when connecting USB items? Some HELP in posting on Computing.net plus free progs and instructions Cheers

I don't get ANY errors....nothing happens, no detection, no configuration, zilch. Can't use any USB.
