Hi to all, I have a problem when installing usb devices drivers the last few weeks. It all started when Windows update tried to install an update for a Logitech webcam and it failed. The error was: Access denied. Since then whenever windows update tries to reinstall the driver I get the same error. Recently, I bought a usb 4-to-1 hub (which normally doesn't need any drivers) and when I first plugged it in I got an access denied error again. Finally, I bought a Canon scanner today and, guess what: Access denied when I tried to install the driver. I am the only user on this computer so I have administrative rights. I also have the UAC off. Any ideas?
