I'm asking this question because it doesn't seem to happen when I reboot from Windows 10.
The problem is fairly simple to explain so here goes, AFAIK when I reboot from Ubuntu (this has been a problem with certain keyboards over the years) my keyboard is not detected during POST. The only way to get it back is to either disconnect and reconnect (works everytime) or power off the PC disconnect the power for 20 seconds and powering back up.
Like said in the first line this does not happen on reboot of windows 10. My opinion is that during shutdown of ubuntu it does not leave the keyboard in a state that can re-initialize correctly during boot. My problem is not that I can't fix this, its that all search engines pukes pages and pages of junk that has absolutely nothing to do with what I am search. Unless someone knows some magical mojo wording to search in google (or anything for that matter) I'm at a loss.
If someone could please tell me where to even look at in my system config to find where such shutdown process regarding USB is located so I can at least start looking into it my self it would be great.
Or if someone happens to know what is causing this issue and how to fix it.
BTW, this has happened on all sorts of makes and qualities (currently happening on a steelseries mechanical ($120.00CND) keyboard). It is running on an Asus x470 chipset but has happened most if not all motherboards I've had for the last 10 years (mostly AMD based systems).
Thanks in advanced for any advice that can be given.
