Just out of interest, can you run the lspci command and tell me how many USB
controllers you have?
I only have one.
00:14.0 USB controller: Intel Corporation 200 Series PCH USB 3.0 xHCI Controller
Two: Intel Z270 Chipset and ASMedia USB 3.1. See below.
This is despite the specs of my motherboard saying.
Intel® Z270 Chipset :
8 x USB 3.0 port(s) (4 at back panel, blue, Type-A, 4 at mid-board)
Intel® Z270 Chipset :
6 x USB 2.0 port(s) (2 at back panel, , Type-A, 4 at mid-board)
My specs are nearly the same, except there are 6 USB 3.0 and 8 USB 2.0,
all listed under Intel Z270 Chipset.
Also, execute 'lsusb -t'.
This will show which Bus Driver the port in question falls under.
