[solved] USB3.0 ports can only detect USB3.0 devicces

[xzpjerry]

Hi, I'm using HP 8470p with 10.10.5 now since it is the last version of OSX that can sleep normally on my laptop.
I followed the guide and everything else works perfectly. But the usb3.0(SS) ports cannot detect USB 2.0 devices now; when I connect any USB 2.0 devices, nothing happens. Considering the limited number of USB ports, it could be problematic.
When I was using 10.12, USB 3.0 ports can detect and use USB 2.0 devices. So there must be something wrong with my configuration and I just couldn't figure it out.

Any help matters, thanks in advance!
