We installed Ubuntu 16.04 on UCS C220 M4 server, which has two USB 3.0 ports at rear.
We connect USB 3.0 devices on USB 3.0 port on the server. However, lsusb shows speed of 480 only.

Question: how to enable USB 3.0 ports on UCS C220 M4 server?

I'm assuming you did the old "sudo apt-get update ; sudo apt-get upgrade" after installing Ubuntu?

Thanks for your reply.
I did not do any 'sudo apt-get upgrade' nor 'sudo apt upgrade', while 'sudo apt update' and 'sudo apt-get update' were executed.

Update only updates the software catalogs and nothing else. You need to run the upgrade option to actually install the updates. Try that. I wouldn't mind betting that solves them issues - and improves your security a lot. You won't even have the security patches installed.
