USB problem
The problem with my build (see my signature) is USB mouse and keyboard actually works fine. Besides that, the front USB 3.0 port seemed to run at USB 2.0 speed and all back USB 3.0 ports did not work at all.

Solution
So basically I followed Norton's solution: a) install GenericUSBXHCI.kext using Kext Utility, and b) copy it to EFI/Clover/Other

Result
All USB ports seem to run at USB 3.0 speed. (I used "seem" because I didn't run a formal test but just eyeballed the rate while transferring a reasonably large file)

I wished I knew before this
Kext Utility, although on its website, says it only supports up to Sierra, it works fine with High Sierra.

Imperfection
In the system report, the USB section still shows "no information" but I don't care.
