PCI controllers and game ports

In the device manager under the “other devices” I have A question mark against it and associated with it PCI communications device. When I remove the PCI communications devive the network adaptors don’t work and I have to re-install the ethernet card.
The game controllers (logitech) are properly installed but adding a controller I am told game port is not properly configured and refers me back to the device manager. How do I fix this?
