How to disable wake up by USB mouse

You can't do that. While the computer is asleep, the hardware can't tell the difference between a button-press on a keyboard and a button-press on a mouse. You could, hypothetically, disable waking on all USB events, but that would also make it impossible to wake the computer via the keyboard.

Go to system preferences>bluetooth>advanced. Uncheck +"allow Bluetooth devices to wake this computer."+

The OP is asking about a USB mouse. Moving the mouse shouldn't wake the computer, only clicking it, and there doesn't appear to be any way of disabling that.

Ooops!

Thanks Roger - I skipped completely by "USB."
