iPod Reverse Tethering via USB I want to use my computer's net connection for my iPod Touch via USB cable.

Creating a wireless AP is not an option as I do not want to setup an AP.

iPod Touch - IOS5.x 
Computer - Win7

Bonus - OSX option as well
From all my research your request is not possible. Only wireless via internet sharing on your windows 7 machine or the mac.
