For backward compatibility, I think is better to leave STROBE(RTS) at pin 6 and the R-switch moved to pin 5.
In real EP I don't know how EGI reacts to the R-switch(I think it is unused, doesn't it?), but pressing it on the unmodified Neos mouse potentially interrupts the flow of data, as it directly joints pin 6(STROBE) with pin 8(0 v).
