I know the B end conector of a Standard USB cable has 4 Pins but the B end of a USB 3.0 cable has a little part added to the Bottom of the B Conector.

 

am I right that this is 4 more Pins?

The USB cable have more because they are backwards compatible for USB 2.0. Both the USB 3.0 A and B ends will have 5 more pins. So they will have the standard 4 pins for USB 2.0 on top, but have extra 5 pins for a USB 3.0 on the bottom. The B cable however had the 5 pins on top and the 2.0 pins are on the square key. Heres a pinout diagram showing the differences to 2.0 and 3.0 and micro 3.0.
