USB tethering lost after installing iphone configuration utility

For the longest time I've been surfing on my Mac (on Lion) tethered to my iPhone (on iOS5). The "iPhone USB" service appears normal in the Network section of System Preferences. After I installed iPhone Configuration Utility (v3.4) the "iPhone USB" service just displays a red dot and I get a "Either the iPhone USB cable..." message.

I found a tip saying I can reboot my Mac holding down the "3" and "2" keys to run in 32-bit mode and this re-enabled the "iPhone USB" service. But this means I have to run 32-bit every time I need to tether?!? I tried uninstalling iPhone Config Utility but the problem persisted.

Is there something I'm missing?

MacBook, Mac OS X (10.5.4)

+1 Same Issue here. Tried reintsalling iTunes, Multiple reboots of Iphone and Macbook. The feature is simply not working. Bluetooth and Wifi Tethering are working fine.

Tried uninstalling iPhone Config 3.5. No luck. Tried installing iphone config 3.2 from a time machine backup file. No luck. Seems we are out of luck until Apple releases a new fix in Iphone config or iTunes. My guess is Network drivers for Iphone got broken

Great solution, fab11 ! It worked, many thanks. I took the /System/Library/Extensions/AppleUSBEthernetHost.kext/Contents/MacOS/AppleUSBEthe rnetHost file from another identical machine.

Fab11, I am not able to get hold of another mac easily to get this file. Any chance of someone hosting it or something? Thanks for all the help though

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

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

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.

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!
