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

Thank you. Unfortunately I will not have access to this computer for some time, will let you know when I can try what you suggest. _______________________________________________ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
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]) Subsystem: Lenovo Device 103c Flags: bus master, medium devsel, latency 0, IRQ 28, NUMA node 0 Memory at 43ffff10000 (64-bit, non-prefetchable) [size=64K] Capabilities: [70] Power Management version 2 Capabilities: [80] MSI: Enable+ Count=1/8 Maskable- 64bit+ Kernel driver in use: xhci_hcd

With the above said, there is another issue that has been vexing me, I have an external USB harddisk and when it is attached the computer fails to boot the OS (CentOS 7.8.2003). After the Lenovo logo all I see is a blinking underscore on the screen. Disconnecting the harddisk at this time has no effect. I have to have the harddisk disconnected when I boot and then connect it, after which it works fine. The only noteworthy thing I am aware of is that is encrypted using LUKS so I have to enter a passphrase once it is connected.
