My USB keyboard was Apple branded.
It's a surprise that after having updated the system to Ventura I could no longer use the usb keyboard even if it is a genuine product of Apple.
I have a MacBook Air 11 inch which was too old to update to Ventura, and this usb keyboard worked flawlessly once inserted.
Obviously this is a system bug and hopefully Apple technicians will solve this problem soon.

Let it sit, still wasn't recognized in the morning (> 8 hours). NVRAM reset requires...wait for it...a functional keyboard.
But on the phone with Apple support this morning:
No clue why this worked, but Apple support said they have seen more reports of 13.2.x and USB accessory issues. Fingers crossed they can get an update out sometime soon. M2 Mac Mini is a week old, not a great experience.
Try the suggested resets.
Hi Dialabrain, I have two wireless Apple keyboards, one connected to Mac mini and the other to MacBook Air. The usb keyboard is connected to the iMac. In order to check how many minutes or seconds it needs for the Mac Ventura 13.2 system to find the usb keyboard, this morning I pulled out the the keyboard and then plugged in and immediately started the time counting, after more than 4 minutes, the system still couldn't find the keyboard, I pressed once every second this key or that key but couldn't input anything. After twenty minutes of trying, I had to reboot the computer hoping that the system would find the keyboard, however the system just kept searching and searching for wireless keyboard , and the plugged-in usb keyboard seemed non-existent . I rebooted the computer more than ten times today, and for once I even waited for more than half hour to see if the keyboard would be recognized, in vain. Now it is almost a nightmare for me, oh no it is a "daymare" for me, to be exact, because all this was done in the daytime from 10:00am to 6:53pm, I couldn't input anything with the usb keyboard.
Sorry, you've lost me. I don't know what any wireless keyboards you have for a Mac mini and a MacBook Air has to do with your original post.
What iMac, model and year are you having an issue with the USB keyboard?
Thank you. I did reset the SMC following for the steps in the link. But it did't change anything regarding the usb keyboard .
I found that with the usb keyboard inserted for the whole night, the following morning the system shows the keyboard hooked. I checked this twice.
I will try NVRAM when I am not in intense use of the computer.
Thank very much again.
Glad to hear it's working for you. I did notice when I switched out my wireless keyboard and plugged in the USB keyboard, there was a slight delay. It wasn't anything like "several minutes" however.
