I'm using Ubuntu 22.04. A few months ago, when still using 20.04, I started having an issue with my mechanical keyboard which until that moment had worked without flaws. This must have happened after an update but since this started months ago I can't retrace which updates were installed prior to this issue starting.
The problem occurs after a reboot and after switching a KVM switch from my work laptop (Windows) to my Ubuntu desktop. The KVM switch is not the issue, the problem also occurs when the keyboard is plugged directly into the desktop PC. The problem does not occur on my windows laptop.
The issue is that the keyboard gets probed and the probing fails; this happens dozens of times.
From journalctl (I have replaced the hostname with [hostname]):

Eventually the probe is successful and the keyboard works:

I have tried other keyboards, other USB ports and a new good quality USB cable as this kind of behaviour could indicate a power issue, and I have tried different power profiles, all without success. The keyboard is a Ducky One2 RGB.
I have seen various posts on askubuntu, stackexchange and others that described similar issues, but all without a final solution. As a result, I spend a lot of time twiddling my thumbs after every reboot or after switching from laptop to desktop waiting for the keyboard to become available. Does anyone have an idea about what might be causing this?
