I was wondering if anyone has this problem. When my MBP goes to sleep with the MX revolution dongle plugged in and I wake it with the keyboard or trackpad, the mouse will not respond. I can take out the dongle and logitech LCC will think the mouse is still connected. I can put the dongle into another usb port and LCC will now think I have two logitech mx revolutions. If anyone has this problem and has a solution to it that would be great.
