Vista - Problem with drivers regarding plug and play devices in vista

My 7 day old computer with windows vista installed, is having problems
installing drivers for my plug and play devices when i plug then in. The
weird thing though, is that my logitech gaming mouse works perfectly, untill
windows asks me if i want to install a driver, and how i wont to do it. When
selecting, "do not install the driver, and dont ask me again" the mouse stops
working.

Im having a problem with an USB storage device as well, the problem is that
windows cannot recognize the device, and im therefore now able to use it. So
i went online to find a driver, but the paradox is, that you cannot find a
driver because it shouldn't be nessecary because the device does not require
a driver if you have windows vista.
