hid_listen doesn't seem to work for some reason.
what's OS are you using? 32bit or 64bit?

• Try other AT(PS/2) keyboard to see if it works.
• Try other Windows computers, Mac or Linux if possible.

I have tried another PS2 keyboard but that one might not work at all. I will have another couple of G80s come in soon that I can test this on.
The same issue happens on another windows PC. If I can find the adapter, I will try it on an android phone and on my friends macbook

Also make sure you are using default firmware. You can download it here.

You will see message like below when the latest version of default firmware.

I didn't see this firmware file before. Thanks for the help. the keyboard works perfectly now. You can add the Commodore to your list.
correction: the issue now happens every couple of minutes or every couple 100 keystrokes.

longer log ouptuts including multiple errors(ERR:20) would be helpful.

ERR:20 indicates timeout error. ERR:13 and ERR:11 are not harmful for XT keyboard.

You may want to check healthiness of hardware.
Make sure connection between keyboard and converter is stable. Try wiggling cable and connector and see if something wrong happens, for example.

And I heard that some people experienced weird behaviour due to bad capacitor on old keyboard. Broken capacitor may cause intermittent issue.

For future reference can you share info of your keyboard?
model name and picture of the keyboard would be useful.
