I just updated iTunes, and got this message: System Extension cannot be used. /System/library/extensions/AppleUSBEthernethost.kext was installed improperly and cannot be used. Any Help?

Same here. I just renamed the offending kext --> ...kext.old and left that folder where it was. I never needed to use the USB-Ethernet adapter on this machine and never will, so no great loss.
