Hello! My Logitech M100 USB mouse keeps freezing up and/or completely turning off - constantly! About every 5 minutes, the mouse just shuts off (the laser at the bottom even turns off) and it becomes no longer operational. To fix it, I have to unplug it and plug it back in. This solution is good for another 5 minutes. Every time my mouse disconnected, I noticed this pop up in the console: Code: 1/15/12 8:27:32.000 PM kernel: USB Optical Mouse::terminate(kIOServiceSynchronous) timeout And, if this is relevant at all: Code: 1/15/12 8:29:10.000 PM kernel: 0 0 AppleUSBCDC: start - initDevice failed Any ideas? Thanks a ton in advance!
