This is a very weird issue which I'm having trouble finding a common thread.
The keyboard is registering keypresses in either the UEFI, or a live Linux USB environment - I used Ubuntu for testing. The keyboard backlight is lit.
The keyboard is registering keypresses in Windows or any Windows-related bootable device. For example, it does not work in Hirens Recue or a Windows 11 bootable installer.
When booted to Windows, not only is the keyboard not registering keypresses, but my USB keyboard is not either!
