I have a HP - Compaq HP 15-d045nr TouchSmart with 3 USB ports. 1 is a USB 3.0 port and it works fine. The other two ports are USB 2.0 and they don't work at all. I don't know how to find them and get them to work. Ideas? Oh, I am using OpenSuSE Leap 42.1 with 4.1.27-24-default kernel and KDE Plasma 5.5 64bit OS.
