 		 #177239 - Forget about it - no bitbanged USB!
Responding to: ???'s previous message
You don't seem to take a no for an answer. Sometimes that is a strength. In this case, it is a huge weakness.

Forget about it!

You do not (!) want to be involved in any software bit-banged USB just to send commands to a microcontroller to perform I2C operations. Get a USB-to-serial interface and interface with any microcontroller. Or get a controller that already supports USB. It is a outerworldly feat to manage bit-banged USB and modifying the code would not be simple. And you will never know when a bit-banged solution will fail because it is living on the margin.
