Hi,

I've created a keyboard driver in asm that interacts directly with IO ports 60h and 64h. It works fine with a PS\2 keyboard.

Although every manual states that USB keyboards work by emulation of a PS\2 like behaviour in order for the processor to be able to interact with it, my routine doesn't even detect any keystroke when using the USB keyboard (nothing happens at port 64h, nor port 60h). Does someone have an idea? I have to make it work..

Thanks for your help.

Nico.
