Q: Personal Hotspot (via USB) not working on iPhone 5 (iOS 7.0.2) with MacBookPro (10.7.5)

Until upgrading my iPhone 5 to iOS 7, I was able to connect my MacBookPro (v10.7.5) via USB cable and use iPhone LTE for internet.  I simply plugged in the USB-Thunderbolt cable to both, then clicked "Turn Wifi Off" on MBP.  I would see the blue bar on my iPhone, and some sort of "connected" icon on the MBP where the Network Icon is.

But now, I'm not seeing a blue, "1 other device connected" bar on the iPhone. 

I rebooted the iPhone.  That didn't work.

Rebooted MBP.  That didn't work

So I dug deeper...

On the MBP, in Network Preferences, I see "iPhone USB" with a status of "Not Connected: Either the cable for iPhone USB is not plugged in or the device is not responding."  Googling that phrase led me to article on a different site with these steps:

• Copy /System/Library/Extensions/AppleUSBEthernetHost.kext to a backup folder (Desktop) and delete the original
• Re-download the latest version of iTunes (http://www.apple.com/itunes/download/)
• Install iTunes, this will update your “AppleUSBEthernetHost.kext” file.
• Disconnect USB-connection to iPhone
• Re-connect iPhone via USB

After doing that, I can now connect Wifi to my iPhone, but still can't connect via USB. 

USB is my preference becasue the hard-line tether was always much more solid and reliable.

So with that in mind, I deleted "iPhone USB" from Network Settings hoping, after a reboot of both devices, that it might recreate it.  But that didn't work.

I also reset the Network Settings on iPhone, which I saw referenced in another article.  But that didn't work either.

Any ideas on what I'm missing?
