Hi Umberto,
Since you are using a wireless manager, make sure that WLAN Auto Config Service is disabled. To do this, click on start and type services, on the top click on Service, then locate the WLAN Auto config, disable it.
Have you tried plugging it to another USB Port? If there are any Devices other than mouse and keyboard plugged in to your computer, unplug them for now. USB devices can cause conflicts.
Try disabling your Anti-Virus or Security Software, then uninstall the device
driver again, this time do it in Safe Mode with Networking by restarting your computer then tap F8 then select this option.
An update will be appreciated.
