I recently bought the ECO Micro-USB wall charger with the 9' foot data cable. It works great as a charger but the cable does not work as a data cable between my phone and computers. The stock charger USB cable work great but is a bit short. With the ECO cable the phone just stays in charging mode as if the usb cable is connected to the charger. Do I just have a defective 9' cable or does this cable truely NOT work with the Bionic as a data cable?
