USB keyboard doesn't work in boot menus
Hi!
Interestingly, my USB keyboard works both in BIOS and in fully booted operating systems - but it doesn't work in the boot menus, for example in Grub or in the boot menu of several linux live CDs. PS/2 always works. Because there is no mouse detection in boot menus, I haven't had the chance to try it out with other USB devices. What could be the reason for that? |
I recently solved this for my wireless keyboard. In the BIOS I had to enable USB in DOS option. In some BIOSs it might be called something else such as Legacy USB.
