Zooming to usb stuff for brevity, tldr version - I think your mouse and keyboard are on the usb3 bus, try moving them to 2.0-based ports?

Here come usb3 ports, I've never had anything but weird issues with xhci devices... Make sure your keyboard is NOT on this.

Here is your keyboard enumerating, seems to register just fine on port 3, which I think is probably your xhci-hub.

Try it on your 2.0 ports. Same with the mouse. Not sure with 3.0, but using low-speed devices usually downclocks the device to lower spec, killing anything else on the hub too unless just using for mouse and keyboard.

These otherwise seem normally ok, look at your xsession and xorg logs further as I don't think the problem is in the kernel, if anything just some evdev regression or something disabling the mouse like my stupid mate issue with mine.
