My system has these:

These are my kernel modules:
lsmod | grep usb
btusb 53248 0
btrtl 16384 1 btusb
btbcm 16384 1 btusb
btintel 20480 1 btusb
bluetooth 589824 41 btrtl,btintel,bnep,btbcm,rfcomm,btusb
snd_usb_audio 278528 1
snd_usbmidi_lib 36864 1 snd_usb_audio
snd_hwdep 16384 2 snd_hda_codec,snd_usb_audio
snd_rawmidi 40960 1 snd_usbmidi_lib
snd_pcm 143360 5 snd_hda_intel,snd_hda_codec,snd_usb_audio,snd_hda_core,snd_hda_codec_hdmi
snd 98304 23
snd_hda_intel,snd_hwdep,snd_seq,snd_hda_codec,snd_usb_audio,snd_timer,snd_rawmidi,snd_hda_codec_hdmi,snd_hda_codec_generic,snd_usbmidi_lib,snd_seq_device,snd_hda_codec_realtek,snd_pcm
usbhid 57344 0
usbcore 290816 9 uvcvideo,usbhid,snd_usb_audio,ehci_hcd,xhci_pci,snd_usbmidi_lib,btusb,xhci_hcd,ehci_pci
This line is important:
usbcore 290816 9 uvcvideo,usbhid,snd_usb_audio,ehci_hcd,xhci_pci,snd_usbmidi_lib,btusb,xhci_hcd,ehci_pci
Notice the last two entries: xhci_hcd and ehci_pci
Those correspond to:
for my two usb 2 controllers:
Kernel driver in use: xhci_hcd
Kernel modules: xhci_pci
for my single usb 3 controller:
Kernel driver in use: xhci_hcd
Kernel modules: xhci_pci
from your lspci:
00:14.0 USB controller: Intel Corporation 200 Series/Z370 Chipset Family USB 3.0 xHCI Controller
This is the sole USB controller in your system and it's a USB 3 controller
so... in your case let's do:
sudo lspci -s 00:14.0 -v
then try:
sudo modprobe usbcore
and repeat:
sudo lspci -s 00:14.0 -v
see if the Kernel driver/module lines change. If they do, plug the camera in and check for it to be recognized in lsusb
