OK.
I own a Renesas PCI-Card that offers 4 USB3-Ports and that worked well
with Linux-Kernels up to 4.8. Beginning with kernel 4.9 it was not
correctly initialized anymore and the problem still persists with
kernel 4.16.2 that I have recently tested.
After a failed start the PCI-situation looks like this:
lspci -vv:
08:00.0 USB controller: Renesas Technology Corp. uPD720201 USB 3.0
Host Controller (rev ff) (prog-if ff)
!!! Unknown header type 7f

While after a correct start with kernel 4.1.43 it looks like this:
08:00.0 USB controller: Renesas Technology Corp. uPD720201 USB 3.0
