How to tell USB 2.0 from USB 3.0 ports? Reward $3
Created by WalterWhite, 1336 days ago, 29782 views

My desktop has like 10 USB ports, how do I know if they are 2.0 ports or 3.0 ports just by looking at them? There is no mark at all. Thanks!

As mdpc said, the device you plug the USB device into should have different signs or colours to show if the actual ports are USB 2 or 3:
USB 2:


USB 3 (the sign on the left image says 'SS' and the usb sign. SS = SuperSpeed as said above):

A USB3.0 Port is Blue, while a USB2.0 Port is Black.

Not all USB 3 ports are in blue.
Read those two article dude:

Yes, I know that, but that method I described would most probably be the easiest to accomplish "just by looking".

Anyway, I believe that most of computers with USB3.0 slots nowadays have blue color, SINCE IT IS MANDATED BY STANDARDS. Therefore, in general, you will determine if it is a USB3.0 slot or a USB2.0 slot (or lower) by its color.

Read here: https://en.wikipedia.org/wiki/USB_3.0

Quoting: "Since USB 2.0 and USB 3.0 ports may coexist on the same machine and they look similar, USB 3.0 specification mandates appropriate color-coding and recommends that the Standard-A USB 3.0 connector has a blue insert (Pantone 300C color). The same color-coding applies to the USB 3.0 Standard-A plug."

Therefore, if a USB3.0 slot is not colored blue (or more specifically, Pantone 300C color), it is a deviation from the standard and should be considered a special case.

I hope this helps you. :)

Hi @WalterWhite ,

The easiest and the fastest way (visual inspection) of knowing/differentiating USB3.0 and USB2.0 Ports is through their colors and markings. USB 3.0 connectors are usually distinguished from their USB 2.0 counterparts by BLUE color-coding of the receptacles and plugs, and the initials SS. However, if there were no markings, the USB 3.0 specification recommends using a BLUE-COLOR scheme (Pantone 300C color) for USB 3.0 Standard-A connectors and receptacles to distinguish them from USB 2.0 Standard-A connectors and receptacles. A lot of times, USB 2.0 Ports use white/black color.

The link below would help you to know more about USB 2.0 and USB 3.0 ports.

If in special cases, there were no markings and no color-coding, visit the site below for further details:

@WalterWhite 1.Open the Device Manager.
2.In the "Device Manager" window, click the + (plus sign) next to Universal Serial Bus controllers. You will see a list of the USB ports installed on your computer.
◦If your USB port name contains "Universal Host", your port is version 1.1.
◦If the port name contains both "Universal Host" and "Enhanced Host", your port is version 2.0.
◦If the port name contains "USB 3.0", your port is version 3.0.

Usb color are usually in Blue and you will notice an increased speed in transferring. If you still can't find your usb 3 ports and want to tell exactly which is which use usb view and check where it says bcdusb (usb version 2.00 or 3.00)
