> 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?
