Not quite :). A 3.0 USB client (like a 3.0 HDD) will usually come with a
new 3.0 USB cable with additional contacts. The client head is different
than with a USB 2.0 cable. The master head (that plugs into the
controller, your computer or hub) is backwards compatible - if you plug
it into an USB 2.0 port, the additional contacts won't connect and the
HDD will speak USB 2.0. The same goes for a 2.0 client in a 3.0 port.
So, controller side, you can plug everything into everything. Only
client side you have a new outlet (which is good because it prevents you
from using an old 2.0 cable and falling back to slow speed if both your
PC and client speak USB 3.0)

Thomas
