The newer A0 BT chip on these cards many times will not work in a x1 slot. Try it in the x4 slot and see if it works or not. The USB 2.0 cable should be connected. You could try the other USB 2.0 header as well.
Thanks @trs96 for this quick answer. Unfortunately the PCI-E x4 slot is completely covered by the GPU (it's a major design flaw on almost all motherboards).
I've tried another USB 2.0 header and it's the same.
It works under windows 10 (PCI-E x1). I don't understand why it doesn't work under High Sierra.
