@kbjfjf4fszojzw – sometimes, on a old desktop, when I restart my computer, it refuses to work with my keyboard (I can’t even use it to make a selection from GRUB)- when that happens, I shut it down using the power button and then turn it back on- then the computer detects my keyboard (this is on antix 19.x, 64bits, on a old single core). I guess some power management problem blocks the usb ports… May be the same problem in your computer…
