I've recently acquired a Gigabyte Z170X Gaming 7-EK motherboard
with the Intel Z170 chipset and Sunrise Point-H USB 3.0 xHCI
Controller for running Linux.
Now most things seem to work fine (some problems with UEFI but
that was kind of expected), but the xhci_hcd module is filling
up my log files with a repeated message (ever 4 seconds):
[ 2137.036187] usb usb2-port1: Cannot enable. Maybe the USB cable is bad?
[ 2137.036981] xhci_hcd 0000:00:14.0: Cannot set link state.
[ 2137.037767] usb usb2-port1: cannot disable (err = -32)
Now I have no idea where usb2-port1 is or why it should have a
bad cable, the only USB devices I know of are the USB drive
I've booted the system from and the wireless keyboard/mouse
combo I'm using.
Both seem to work just fine and plugging those into different
USB ports doesn't change the message.

Note: I have no idea what the Hitachi device is.
The current kernel is 4.14.13 (from Mageia 6).
Any idea what the problem here is and how I can fix or work
around it?
Please let me know if you need any additional information on
the system or environment.
lsusb -v could show more details about the misbehaving device.
Output of dmesg could tell something as well
