USB tethering lost after installing iphone configuration utility

I'm also having this issue, got no other place to copy the file from 😟 really hope that apple fixes this issue soon.

Fab11, after replacing my original file with your emailed one, I get this error message when I plug in my iPhone and turn on tethering:

"System extension cannot be used

The system extension “/System/Library/Extensions/AppleUSBEthernetHost.kext” was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update."

I noticed that in the Get Info for the file you sent me that under More Info it acknowledges in the Where From that you sent it to me and it says your name and email address. I removed this by duplicating the file. I also noticed, however, that it says my permissions are 'custom access', despite me unlocking it and setting every user's access to Read & Write. Any ideas?

After tweaking my permissions on that file (back to Read & Write for Admin), I now have USB tethering functionality restored. +kudos to fab11 ! Many thanks

HI fab11, please send me tha file too: t.muller@mito.hu THX!

Hi fab11, please, i also need the file. I make a mistake, i also replace "AppleUSBEthernetHost.kext" from a backup time machine and right now i have a problem with the permisions

Hi. Thx fab11. Finally I managed to do it without the given file. My solution:

1. Delete iPhone configuration utility.
2. Do fab11's magic:

sudo rm -rf /private/var/db/receipts/com.apple.pkg.iPhoneConfigurationUtility.*

rm -rf ~/Library/Preferences/com.apple.iPhoneConfigurationUtility.plist*

3. Delete the whole folder: /System/Library/Extensions/AppleUSBEthernetHost.kext

4. Reinstall iTunes (just over the previous one)

5. Restart

Thak you very much fab11, i can´t repair jet, but i´ll try this night. I have problems whith your file, i don´t now why, the permission it´s ok, the error mesage also say me error whit the instalation, the size of my orginal its 52K and the size of your file is 133K...

Thanks

Worked like a charm for me.

I didn't need to do rm -rf ~/Library/Preferences/com.apple.iPhoneConfigurationUtility.plist* as there was no such file.

Copied the file from a wife's mac.

It will not work unless permission match. So rather than muck around with chmod, I simply did a "Repair Permissions" in Disk Utility.

Worked like a charm.

Hi, finaly my tethering works perfect!!! thanks for fab11 and muellha.

Best reegards

Thanks a bunch! Finally it is working again!!

I wonder if todays iTunes update will fix this for those that haven't got it sorted...I had mine start working last night,matter I think I deleted the whole jest file and contents and copied from my macmini server

Thanks muellah and fabs. This works perfectly.

Many thanks to you all! I lost my USB tethering one week ago and I have almost gone mad, first to find the root cause and then to find a solution.

My love to you all!

I have the same problem, I tried to uninstall it but the problem remains the same. And I don't know how to set

file://localhost/System/Library/LaunchDaemons/com.apple.usbmuxd.plist. Any one can help me!
