go to system and see if the dongle is listed and has a yellow mark by it. If so click on update driver. If not find the equipment with the error message and delete/uninstall it. Reboot pc with dongle disconnected and check that no reference to it exists. Then reboot and when running normally insert dongle and it should be found and installed. If none of this is possible look in system and see if the usb root hub has any yellow marks - you may have to run the mobo installation cd to install the drivers.
