Identify the devices correctly in Device Manager and download the correct drivers for the devices into a separate file (only so you can navigate to it). They will probably be available from your laptop manufacturers web site.
Then, remove both devices from Device Manager and reboot the laptop.
You should get the "Found new hardware" message. Point the installation program to your downloaded drivers and reinstall.
Alternatively, do a search for your laptop model and see if there are any known problems in this area.
