Over here the iPhone USB interface in the Network pane also keeps displaying 'not connected' when the USB cable is connected to the iPhone.

  • Mac OS X: 10.6.8
  • iPhone: 4
  • iOS: 5.1
  • iTunes: 10.6.3
  • iPhone Configuration Utility: 3.5

The cause is a faulty /System/Library/Extensions/AppleUSBEthernetHost.kext, though the version 2.3.0 is correct, its size of 78 KB, 60.892 bytes is not.

A known to be working AppleUSBEthernetHost.kext for iPhone USB tethering is version 2.3.0, but 225 KB, 189.646 bytes.

The fix is:

  2. Restart (not sure whether this is necessary)
  3. Reinstall iTunes (in our case 10.6.3), this also installs the good AppleUSBEthernetHost.kext. Just: download iTunes from https://www.apple.com/itunes/ and run the installer, this will install the correct AppleUSBEthernetHost.kext.

When tethering still doesn't work:

  2. add the iPhone again
  3. hit the [Apply] button
