I own a Compaq Presario v6305nr notebook. Now I have had problems with it in the past (bad mobo, HDD, Wireless Adapter, etc...) but eventually they all got replaced, and I was happily running on Windows XP. However, one day last week, all of my USB ports stopped working. When I would plug a usb device such as a flash drive into them, the drive's LED would light up briefly while it was being inserted, and then stay off. The computer would not recognize that any USB device was there. I figured it might be the drivers, since there are no real XP drivers for my type of computer. So I figured I would reformat it to Vista, which it came with. After doing that, they still don't work. Device Manager says there are no problems with the drivers, and the only drivers that I don't seem to have are 3 Base System Device (?), and 1 Unknown Device. I read to leave the computer unplugged from all power sources overnight to reset the cMOS, and that didn't work. I tried to locate legacy USB in my BIOS, but it was nowhere to be found (PhoenixBios). I really don't know what else to do. I'm sorry if I left out any kind of detail, if I did please let me know, and I will provide it. Does anyone have ANY ideas at all?

EDIT: I just installed/updated the touchpad, modem, audio, and card reader drivers. This got rid of the 3 Base System Device drivers that were previously mentioned.

I would try...going to Device Manager and uninstalling all USB controllers (not hubs, not devices) reflected there...then rebooting.

I tried doing all of the above, including what was on the Microsoft site. It looked promising at first, but the USB drives still act the same. Thanks for the reply, can anyone think of anything else?
