I accidently had the Belkin Wireless G USB Network Adapter plugged in before I installed the software on a customer’s computer. I tried to fix it (a lot of times) by uninstalling, disabling, reinstalling. It was all in vain. After waiting 10 minutes on hold for tech support, I basically have to clean install Windows. Man, no mercy! I spent over an hour on it, too!
On the box, they should clearly say that if you mess up, you’ll have to format everything: in big, bold letters. Ugh! Idiot!
