Microsoft has released a firmware and driver pack for the Surface Pro 2 device.
There is no information on whether or not these have any updates on the current drivers per-installed with the device (I doubt it), but if you clean install for some reason, and missing drivers, download and install this, and you should be good to go.

I think it's definitely something that all SP2 users should get and stored somewhere.
