I get a message from system telling me that
/system/Library/Extensions/Apple USB Ethernet Host.kext was installed improperly and cannot be used.Please try reinstalling .
Where do I get the software and how do I proceed?
Got that after last Itunes snowleopard updates.
Please help.

MacBook, Mac OS X (10.6.7)
First thing to try is to apply or reapply the 10.6.8 Combo update.

Other than that, you will have to use Pacifist to extract it from the Snow Install DVD
EDIT: long thread on this here, with some possible fixes. Seems to be associated with the iTunes update.
G wizz!
An answer.Thought I'd never get one!Snow leopard is quite old now.But I like it.Will look into the combo update.
A zillion thanks.
Syld
The Combo update doesn't include that particular kext file. However, it can be extracted from the original SL install.
I can locate Extensions/Apple USB Ethernet Host.kext .Would it be OK to move it to the trash? What do I do next? Do I have to reinstall last iTunes update.
Syld
Yes, move it to the Trash. Then download and install iTunes from the Apple web site: http://www.apple.com/itunes/download/
If you watch the location in the Extension folder, you will see that the installer will replace the kext file during the installation process.
Then restart your Mac.
how could you move that to trash? when i want to open that folder, system shows me message: The folder “AppleUSBEthernetHost.kext” can’t be opened because you don’t have permission to see its contents. 😐 how can i fix this? thanks ... (i already have the latest iTunes update, but my mac still shows me this message)
when i want to open that folder, system shows me message
You're not trying to open the kext file, you want to drag it to the Trash. You will be prompted for your admin password. The when you re-intall iTunes, by using the download from the Apple web site, not by using Software Update, the kext file will be replaced by the iTunes installer.
but i don't know where I can find this file?
Double click your Macintosh HD icon, open the System folder, then open the Library folder, then open the Extensions folder, look alphabetically for the file.
The path name is provided in the title of this Post's subject.
Source for the iTunes download: http://www.apple.com/itunes/download/
thanks a lot, Lanny 🙂 i find it.. so i can put this .kext file to the trash and re-instal iTunes, and it will be ok?
It worked for me, and most others.
Some people have reported that it didn't work for them, but I have no way of verifying that they followed the procedures correctly.
Same thing happened to me (10.8.5). I installed the iTunes upgrade to 11.4, then the hot spot on my iPhone stopped worked via USB. Your solution worked perfectly. Thanks.
it works for me!!! thanks a lot brooh 🙂
fixed it for me. Tx
Its works for me.
But i need to re-start the computer.
Thanks Lanny for your solutions.
Cheers
