Linux How can I find out if the server has USB2 or USB3

Question

I have a server that I do not have documentation and I plan to buy a USB Storage Device that is USB3 and now I want to find out if the server has USB2 or USB3.

I tried

dmesg | grep usb

From your logs it looks like the system has EHCI USB controller. This means USB2. Try grep for XHCI.

I would use the information provided by dmidecode -t 2 to find the model of the motherboard. Then you would probably be able to find the specs online.

Thanks to Krasi I discovered the dmidecode, and the option :

dmidecode --type connector

so I have 4 USB 3.0 Ports
