Im having a weird problem with OS 10.7.5/2009 flashed MPro which I can't track down. I noticed the intermittent problem a week ago and it has seemingly become worse. The mouse will stop functioning. If I remove it and plug it in to an external usb 2 port it usually starts functioning again. Today it happened and did not respond to the usual fix so I had to hard restart with the power button and found the keyboard was out for lunch as well after booting up. I tried different mice and a different keyboard; none solved the problem. Second hard reboot brought things back as I was able to select startup disk by pressing option.
I tried all usb ports on the Mac Pro when the mouse and keyboard blacked out and surprisingly, none worked even though I had just been printing from two of them. I know my second mouse and keyboard are ok as well.
Could this be some kind of conflict. Seems OK now but I want to trace it down.
At this point all I have is that it doesn't seem to be hardware. Any insights appreciated.
