AppleUSBEthernetHost.kext was not installed properly

Whenever I start my Mac mini I get an message that says "AppleUSBEthernetHost.kext was not installed properly. Reinstall or contact the vendor ..." I'm not sure what this does, as it does not seem to interfere with my operation, but I like to take care of error messages.

MacBook Pro, Mac OS X (10.6.8)

Open the Script Editor in the /Applications/AppleScript/ folder, copy and paste the entire following line into it, and press the Run button:


do shell script "chown -R root:wheel /System/Library/Extensions/AppleUSBEthernetHost.kext" with administrator privileges


If it doesn’t work, choose Go to Folder from the Finder's Go menu, provide /System/Library/Extensions/ as the path, throw the AppleUSBEthernetHost.kext item away, and reinstall iTunes.
