I have a Compaq Presario CQ62-215DX, running Norton Internet Security and firewall through Windows 7. I sucessfully installed new Wireless LAN and Lightscribe system software several days ago, along with the Live Essentials, Realtek and Windows 7 Updates.

Everything was operating correctly yesterday, but when I booted up my computer today my wireless mouse refused to work. After trying a fix involving a USB stick, I realized that none of my USB ports work. The ports light up when I restart, until Windows 7 finishes logging in, and once it begins the drivers refuse to work. Is it because of the recent updates? Because I cleaned up my back-up copies? Any help will be apprecited!

Have you tried disabling and re-enabling all of your USB controllers and ports in Device Manager?

If you don't know how to do get there...
Start menu > Right click on Computer > Manage > Device Manager

Moreover, to disable USB ports, go to the Universal Serial Bus Controllers button in the Device Manager. Right click each individual one and click disable. For each one. Then after each one is disabled, start from the top and do the same thing but click Enable this time. There are some dependencies in there sometimes that will disable more than one individual device, so be aware of that.

It keeps saying it sees it, but it can't disable or enable it because there's another version in the computer (and it won't show that other version to disable it) :/

When I shut off the computer and flicked it back on, for some reason my virus protection has stopped working; the antivirus and antispyware buttons on my Norton are turned off and greyed out, so I can't turn them back on. IDK if it's all related?
