The one thing USB was never designed to be used for is networking and you are at the mercy of every other USB device you may have used in the past and/or are using now. If you had another USB wireless, have you uninstalled its software? If you have retired any printers, did you uninstall their software, too? (Older Dell/Lexmark software, in particular can wreak havoc)
Once you have uninstalled any older device software (things you don't have anymore), try turning the PC off, unplugging everything else USB (except a keyboard and mouse), then fire the system up and try it again.
But; if you want reliability, get a PCI card for a desktop or a PC-Card/ExpressCard for a laptop. Then your networking won't be messing up your USB.
