Q: iPhone USB Tethering suddenly stopped working on OS X Lion

Yesterday, I updated the iPhone configuration utility to v 3.5 and I was using the internet via iPhone USB tethering, as soon as the update finished, my iPhone USB tethering stopped working and its not working any more. I am on OS X Lion 10.7.3 using iPhone 4S, iOS 5.1.

 

Now I figured out that running the OS in 32 bit lets me do USB tethering, but in 64 bit the iPhone USB Network Service shows on the right:

 

"Either the cable for iPhone USB is not plugged in or the device is not responding."

 

I've tried everything with keeping iTunes running, reinstalling iTunes, re-installing iPhone configuration Utility, but nothing seems to work!  I guess the main culprit here is the new iPhone Configuration Utility v 3.5. It is so annoying to see such things breaking existing functionalities. It has nothing to do with my Phone, because it works on my other Macbook Pro which I did not update and on my friends Snow Leopard.

 

Anyone has any ideas how to fix this problem? Any help would be appreciated a lot!

MacBook Pro, Mac OS X (10.7.3), iPhone 4S v 5.1

    My Bluetooth and Wifi were working, but there was no interface for the USB. Bluetooth and Wifi were unreliable and I wanted to use USB for a faster, better connection. My problem was the iPhone USB was not showing up under Network Preferences.

     

    What did not resolve the issue:

    1. iOS: Troubleshooting Personal Hotspot

    2. Downloading AppleUSBEthernetHost.kext from Mr. Dopey

    3. Using Time Machine to go back to December 2013 to restore AppleUSBEthernetHost.kext

    4. Updating iTunes (can't delete it)

     

    What worked:

    Using Time Machine to go back to my oldest back up (Jan 2012) to restore AppleUSBEthernetHost.kext

     

    Just in case someone else like me starts thinking it isn't the AppleUSBEthernetHost.kext:

    Some other website suggested checking the AppleUSBEthernetHost.kext file to see if it was the problem.

     

    in terminal:

    file /System/Library/Extensions/AppleUSBEthernetHost.kext/Contents/MacOS/AppleUSBEth ernetHost

     

    This was my output:

    /System/Library/Extensions/AppleUSBEthernetHost.kext/Contents/MacOS/AppleUSBEthe rnetHost: Mach-O universal binary with 2 architectures

    /System/Library/Extensions/AppleUSBEthernetHost.kext/Contents/MacOS/AppleUSBEthe rnetHost (for architecture i386):    Mach-O object i386

    /System/Library/Extensions/AppleUSBEthernetHost.kext/Contents/MacOS/AppleUSBEthe rnetHost (for architecture x86_64):    Mach-O 64-bit kext bundle x86_64

     

    After replacing the AppleUSBEthernetHost, my output is exactly the same. The above command is not a good indicator for this situation:

    /System/Library/Extensions/AppleUSBEthernetHost.kext/Contents/MacOS/AppleUSBEthe rnetHost: Mach-O universal binary with 2 architectures

    /System/Library/Extensions/AppleUSBEthernetHost.kext/Contents/MacOS/AppleUSBEthe rnetHost (for architecture i386):    Mach-O object i386

    /System/Library/Extensions/AppleUSBEthernetHost.kext/Contents/MacOS/AppleUSBEthe rnetHost (for architecture x86_64):    Mach-O 64-bit kext bundle x86_64

     

     

    Maybe it's like a blood transfusion. Sometimes blood from other people works and sometimes you just need your own stuff.

    I have a iPhone 5S, Macbook 2007, Lion. I am able to connect with all three at once.


    Cheerio!

    Works 100% (KextUtility FTW!)...

    (iOS 7, iPhone 5, OS X Lion, MBPro mid 2010)

     

    Thank you, forums (and get on top of your code, Apple!)

    I had to return to this thread 2 months later, because the USB tethering stopped again. The AppleUSBEthernetHost.kext was the same file from January 2012 and had not been modified. I used TimeMachine again to get the same file and rereplace it and it works again. It works again, and now I'm keeping the file on my desktop...
