While trying to reinstall printer drivers an error message popped up saying: 'Systems Extension "/System/Library/Extension/Apple USBEthernetHost.kext" was installed improperly and cannot be used. Try re-installing this.'
What's happened and how do I fix it please?
I'm using a 15" Macbook Pro, mid-2012 with OSX 10.8.5
