Can a usb 3 port come in black color?
<p>I have some doubts about one of my (new) laptop's usb ports regarding whether it is usb 2 or 3. </p>

<p>The port color is black, while it is reported that usb 3 come in blue. 
From ubuntu 14, I checked with <code>lsusb</code> and I got</p>

<pre><code>bcdUSB               3.00
</code></pre>

<p>which should mean that the usb port is version 3. Does the black color mean something?</p>
