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

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 :laughing:

Cost cuts probably :man_shrugging:
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

usb3-2

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…
