Without other usb devices the keyboard works immediately. With them it takes 5 ish seconds for it to start responding. This is regardless of which device is discovered first (which I can manipulate), it seems to just wait for all of them. Is there a way to make it not do that?
Edit: This is specifically about linux boot. It otherwise works fine in bios / bootloader
I believe this is a hardware issue. Have you checked the USB options in the BIOS?
It works fine in bios and bootloader. This only happens during boot
Your title indicates otherwise so might be worth amending it.
