I am not able to use my USB keyboard in Grub screen of my laptop. It works in BIOS, Windows and lubuntu.
What I've tried:
- changing everything that I could find related to USB in BIOS.
- adding GRUB_PRELOAD_MODULES="usb usb_keyboard ehci ohci uhci" GRUB_TERMINAL_INPUT="usb_keyboard" to /etc/default/grub. and ran grub-mkconfig.
What works:
- Using my laptop keyboard instead of USB keyboard.
- disconnecting and reconnecting the USB keyboard when I'm on Grub screen every time.
Grub version: 2.02~beta2-36ubuntu3.28
