Wired keyboard problems with m1 MacBook Pro 14" 2021

I have a 13" MacBook Pro with Monterey and have the same issue. My old USB-A wired keyboard suddenly stops working. The solution I found is wait for 2-3 days and then connect the cable and it works. Since my keyboard is old I believed it was malfunctioning however I also have Air where it works perfectly.

Any recent solution?

interestingly I have a similar problem with my 1 month old BTO MBP. I would add that my wife had the same problems with another wired keyboard swapped between 2 intel iMac 27's which we have at home. She managed to get the wired keyboard to work again by 1st connecting a different wired keyboard to the mac she was using. Next she simply disconnected the 2nd wired keyboard, reconnected the original wired keyboard and it worked.

So.. I did exactly that on my MBP 14 inch. The 1st wired extended apple keyboard stopped working without any notification. I 1st tried connecting it to different ports ( I use a USB C to USB A adapter). The keyboard didn't work on any of the 3 USB C ports.

Next I connected another wired extended Apple keyboard to my MBP, it worked fine. ( nI did receive a message saying a new keyboard has been detected and to press the key to the right of the shift key to identify the keyboard) I then disconnected that and reconnected the original wired extended apple keyboard and guess what, it worked with no problem.

I have not had the problem again since but wondered in light of the notification, if there was a software/hardware error which failed to recognise the keyboard?

Perhaps someone with more technical expertise can understand what is happening.
