Historically speaking yes, but on at least some laptops the built-in
keyboard uses PS/2 and looks like an i8042 to software. The BIOS can use
SMIs to emulate a PS/2 keyboard when a USB keyboard is used and the system
hasn't yet indicated that it understands USB. That could be the case if
U-Boot was being used more as a bootloader and there was a traditional BIOS
underneath that did fancy things like that.
