These are my kernel modules:

This line is important:

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

Here is the output from tail -f /var/log/messages:

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.

On the recommendation by Lenovo, the motherboard has been replaced but the Logitech C922 is still not recognized by the USB subsystem when connected. However, I have now tried Ubuntu 20.10 Live running off the DVD and it does recognize the webcam.
As stated earlier, I have two laptops running CentOS 7 and both recognize the same webcam, thus no high-level deficiency in CentOS 7 itself.
Thus, the problem is not with the hardware, the webcam or the computer, but maybe there is some low-level code for the USB subsystem missing in CentOS 7 required for the Logitech C922 to work on this Lenovo ThinkStation?
What is the opinion of someone more knowledgeable than myself?
