Go to device manager and delete both items. Restart your computer and see if the problem is resolved. If not you have to download fresh driver for the ethernet card and when installed, this will now look normal in the device manager. If the 'other devices' is still present click to remove the 'other devices' again.
Hopefully this will rectify the problem your friend have.
In case you friend hasn't got a seperate ethernet card and it is on the mother board itself then you have to down load it from the manufacturers site of the mother board or if he has the software cd came with his system he can run installation from that.
