Not quite :). A 3.0 USB client (like a 3.0 HDD) will usually come with a |
7 |
new 3.0 USB cable with additional contacts. The client head is different |
8 |
than with a USB 2.0 cable. The master head (that plugs into the |
9 |
controller, your computer or hub) is backwards compatible - if you plug |
10 |
it into an USB 2.0 port, the additional contacts won't connect and the |
11 |
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 |
14 |
client side you have a new outlet (which is good because it prevents you |
15 |
from using an old 2.0 cable and falling back to slow speed if both your |
16 |
PC and client speak USB 3.0) |
