Yeah, it will do... as the switch contacts move it glitches the power
supply and screws up the processor inside the mouse. The hardware hack
to get round this is to stick a big capacitor (>=1000uF) across the
power pins on the common socket (pin 4 = +ve, pin 3 = GND).
Depending on how good the emulation carried out by the USB-PS/2
adaptor is, you may be able to un-glitch it by exiting X, executing
echo -ne '\377' > /dev/psaux and starting X again. This does a reset
on a native PS/2 mouse; if the adaptor's good enough it should
translate this into a reset of the USB mouse.
I know it's not quite what you're looking for, but it might get you
going.
