I purchased and installed the windows 7 vista upgrade the day it was released. Everything was working great, until one day all the USB hubs decided to quit on me. In device manager the following message appears; Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19). I tried updating drivers, deleting drivers and reinstalling them, I also went as far as deleting low and high filters in the registry. I finally decided to restore my system to the time I updated to windows 7, and this finally worked! Until a couple days later, and now Im right back to where I was with absolutely no USB's.
Can anyone help me with this problem? Can I reinstall windows 7 all together? This is driving me nuts because I cant use my wireless mouse/keyboard or my external hard drive. Please help.
