Hmm, did not have an opportunity to try your suggestion at the end of message until today - after I did a BIOS update. The BIOS update, by the way, resulted in the complete loss of recognition of the Logitech camera, regardless of which USB ports I am trying...
Anyway, your suggestion above follows:
#lspci -s 00:14.0 -v
00:14.0 USB controller: Intel Corporation 200 Series/Z370 Chipset Family USB 3.0 xHCI Controller (prog-if 30 [XHCI])

# modprobe usbcore
# lspci -s 00:14.0 -v
