Correct. He cannot guarantee or count on getting any resultant action be timed exactly together. There will be a number for maximum delay between the two events. It will be a worst case add-up of the two periods which the mouse port or USB-to-mouse port get polled at.

Maybe even synch it to GPS or something...? I know better than to ask why the OP want's to mouse-click two computers simultaneously!! But I must admit, I am just a tiny bit curious..... :)

PS/2 mice use an interrupt. You big dummy. Do interrupts not also get polled in cyclic fashion? Can you guarantee that both machines will poll their respective interrupts at the same moment? When was the last time you saw a new PC or laptop that had a PS/2 mouse port? They do, but more often, they are made without them at all. There are USB mice that plug into USB ports, and no PS/2 port is anywhere to be found. Those to are polled, and any such polling would be asynchronous with a separate device not triggered by the same clock. You might think it worked "at the same time" but it in fact cannot be. There will always be some difference.

That too is sad. |
