[LUG] New computer not seeing the keyboard

[Neil <barnaby@xxxxxxxxxxxx>]

Recently I bought a new desktop computer, just the tower, not the 
monitor or keyboard which are quite new. It came with a version of 
ubuntu installed, which I replaced with the latest version of MX Linux.
That all went very well until this week when suddenly the machine 
stopped seeing my keyboard. The mouse was fine, but the keyboard was 
ignored. As the keyboard is plugged into a USB port I tested it by 
plugging it in to some of the other ports. No good, still ignored.
I also have a laptop. I don't like the keyboard on a laptop so I have a 
cheap keyboard plugged in to USB. So I tried that keyboard on my desktop 
computer. Fine, that worked perfectly, in fact it is what I am using 
now. So I tried the first keyboard on the laptop. It worked just fine.
So I have ended up with a cheap (£9) keyboard which works on both 
computers, no problem. I also have an expensive (£120) keyboard which 
originally worked on the desktop but now works on the laptop only.
My only thought is that one of the updates which I have run on the 
desktop since installation have made some sort of change to a driver 
which has caused this problem. If anyone on the list can offer some 
ideas about this I would be very grateful.
Thanks,

Neil
