Restriction and Bug
-------------------
Not statble yet.
Can't bus-reset a keyboard which already attached on bus properly.
Slow start up of Leonardo's bootloader causes this?
Need to unplug/plug a keyboard after firmware starts up.
MAX3421E doesn't work SAMPLEBUS well to know whether device connected or not.
Keyboard with other endpoints than boot keyboard may go wrong.
On my keyboard with mouse key the converter locks up when using mouse key function.
