Clear up some USB confusion

* The USB branding is not consistent. Please take a read of the spec
  rather than random websites to provide more consistent terminology.
* The point of client-side cables is the
  single-cable-development-experience. It should be consistently
  highlighted.
* There is no "BeagleBone-X15". BeagleBoard and BeagleBone are not
  interchangable terms.
* For BeagleV-Ahead, it is important to note it is a type-AB receptacle
  because it can act as both a host and client at super-speed. This is
  the reason we put on the somewhat rare micro-AB connector--we want
  people to be able to use it both ways without violating
  specifications or requiring extensive software configuration.

+USB Data/Power Cables
+***********************
+
+For all Beagles, there is a USB client, also called gadget, capable connection that will enable you to
+create network, serial and data storage connections from a host computer.
+
+In most cases, you can also provide power over this same cable.
+
+In most cases, you can also use the port in a host mode, also sometimes called on-the-go to refer
+to when a device that is typically a client can also act as a host.
+
+Cable included?
+===============
+
+A USB (High-speed A to Mini-B) cable will normally be supplied with BeagleBone Black. For other boards,
+you'll have to procure your own USB cable.
