Zoltan, you might want to test this series with your Pegasos2 machine. It makes the keyboard detected correctly. There is still a problem with the mouse interaction with the host. Pressing Ctrl+Alt+G to ungrab the mouse, my host mouse is still responding to guest events... (unrelated to this series). Tested-by: Philippe Mathieu-Daudé <f4...@amsat.org> (PPC Pegasos2 so far)
