I'm a Ubuntu 10.04 user. What's the fastest way to tell if the two USB ports on my computer support USB 3.0? I'm not sure if they're 2.0 or 3.0, and I need to know. Thanks!

    Manufactures have taken a liking to making 3.0 ports blue, can't be sure of always though. Feb 27 '11 at 3:51

    My USB3.0 port is blue and has the extra pins - my USB2.0 only has the 4 pins, but is also blue

First be sure that your motherboard SAYS "Supports USB 3.0"

Then you can for example go to the terminal and type lsusb and it will show the version of the usb.

Another can be lshw but it shows a lot of info

If you want super full info then do sudo lsusb -v this should give you whole information about all ports and anything connected to any usb port.


Just look at the ports on the machine and if they are blue-ish then it is USB3.


Look at a USB 2.0 port.

It has a black "tongue"

A USB 3.0 port has a blue one.
