Mouse and Keyboard must be unplugged and replugged to work

[Geophyte1]

Lately, I'be been having to unplug and plug back in my mouse and keyboard to get them to work at the log-in screen.

I've been using the same mouse and keyboard for a few years without a hitch until now.

The problem has also come and gone a few times over the last two or three months.

Any ideas?

Thanks

I just realized that this problem seems to have gone away. I have no clue why.

I did let CCleaner run somewhat free recently but I can't remember if it had gone away before or coincident with it.
