@wiktormowinski SeaBIOS is very tight about the USB timeouts. Try to set SEABIOS_USB_SIGATT_TIME in coreboot config to 1000 (milliseconds) or more. Default is just 100ms, which does not always is enough to detect all devices.

i've tried with 3'000, 30'000 and even 300'000 and it seems like this option just elongates boot time and doesn't help the keyboard problem unfortunately

So it turns out USB keyboard does work reliably in firmware (PiKVM), but having PiKVM plugged in and adding another one doesn't. That's because SeaBIOS only supports one USB keyboard at a time.
EDIT: confirmed, can be closed

Yes, SeaBIOS is not that smart.
