Two days ago, I started having two intermittent problems that are probably related (given the timing):
(1) my MBP stops talking to my Logitech mouse... I can still move the mouse cursor via the track pad, but it won't see the mouse until I unplug it from the USB port and plug it back in... very annoying... happens every 5 to 15 minutes of use
(2) less often, my mouse cursor will stop responding for about 20-30s... and when it starts responding again, problem #1 always occurs (the connection to the mouse is lost, though the trackpad still works fine)
As a result, I restarted the machine and updated all my software.
But the intermittent problems remain.
Any suggestions?
