The 'generic' FourThirds to Micro-FourThirds adapters I've seen have no electrical connections. They are designed to be useful for adapting manual lenses that have already been adapted to FourThirds mount onto Micro-FourThirds cameras.
If you want to use FourThirds SLR lenses on a Micro-FourThirds body, buy the Panasonic DMW-MA1 or Olympus MMF-2. They are what you need and are identical in function.
