Got my new Pyboard - plugged it into my PC (windows 7)
I get
1) mass storage device - OK
2) uPy microSD flash USB drive - OK
3) Pyboard virtual Comm Port in FS mode - No driver found

What driver should I use?

You should find the necessary .inf file on the file system that your pyboard serves (via mass storage) when there isn't an SD card present. (When Windows is looking for a driver, tell it that you want to look in a specific location and point it at the root directory of the removable disk that represents the pyboard's mass storage device.)

I initially ran into the same problem. A friend helped me craft one from the template in github this morning. I discovered the one on the pyboard this afternoon.
