If you have ever plugged in a USB device (and who hasn’t), you must have at some time fumbled with plugging it in the right direction since the connections look pretty much the same on both sides. But don’t count on using it with existing USB pugs because it won’t fit because it will be smaller than today’s USB plugs and closer to Micro USB size.
There is going to be a complete redesign of the USB Type-C connector for USB 3.1 devices. The new connector will also be able to distribute power to devices without the need for a separate connection like you see in many dual USB devices. The specifications for USB 3.1 include a 10 Gbps data speed which is twice that of USB 3. This will come in handy for today’s HD video playing and large file transfers.
Expect there to be adapters to be able to connect between the cable types. The specifications of the USB 3.1 are expected to be finalized by Summer 2014 so don’t plan on seeing any USB 3.1 devices or cables until after that.
