How do I know if the USB ports on the front on my desktop is USB 2 or USB 3?

[arch_lover]

Hi,
I have 6 USB ports mounted on my motherboard. 4 of them are black which afaik are USB 2.0 ports & the remaining 2 are blue which indicates USB 3.

There are 2 USB ports in front of the cabinet connected by a header cable which is connected to the motherboard. These 2 ports are black in color.

Since they are not mounted on my motherboard I am not sure if I should judge them by their black color.

Any command that can confirm ?

Check the motherboard manual, then check the case front panel specification.
If the motherboard has a different version than the one that is present in the front panel, the slower of the two will be the speed.
In my motherboard B550-F gaming, I have 2 x ports USB 3.2 Gen 1 pins, but my case front panel is 3.0 only, so it will work at 3.0 bandwidth.

If you’re not sure which of those hubs are from front panel - connect something obvious to it (usb dongle, mouse - whatever), then run this command and see under which hub your device is listed

SanDisk Cruzer Blade is the device that I have connected for testing.

Seems it’s Hub-1: USB 2.0 / 480 Mb/s then

Usb 3 ports are almost always blue internally.

I wonder why Asus decided to make the front USB ports 2.0.
I mean they could have easily made the header female port 3.0 so that the front ports can get 3.0 speeds.

I have DELL laptop which doesn’t give a crap about blue internals, but is 3.0

Cost cuts probably
Also it depends on age of hardware

You know, usually to cut costs people cut peripherals, materials quality etc, stuff that’s not obvious for most people.

A USB3 cable from the case mounted USB ports will have a connector that will look like this

A USB2 cable from the case mounted USB ports will have a connector that will look like this

I HATE it when some manufacturers make USB 2.0 ports blue. That triggers me almost as badly as someone using #!/bin/sh for Bash scripts…
