Yes, if you enable USB support in L4Linux than the USB host controller
will be reset and the USB legacy support will not work anymore. What you
can do is also start the usbhid server (usbhid package) which implements
the USB keyboard/mouse driver. Do not enable USB in L4Linux then.
With usbhid the system should also work with USB keyboard and mouse.
