    Everytime my MacPro goes into sleep mode (either from activity for from me manually putting it there) it immediately clicks awake. Strangely, when I'm booted into Vista, it sleeps like a baby. Is there a way to figure out what is triggering this?

    I have a few wireless devices plugged in (mouse, keyboard, display) and bluetooth is off (I'd read that bluetooth headsets are a common culprit).

    Thanks in advance for any advice.

    The Console should list what caused the system to wake.

    Open Console.app (/Applications/Utilities folder), and check the system.log file. Scroll up to the last time it woke up when it shouldn't, and see what it says. It will say here why it woke up.

    Wake reason = HDEF EHC1 EHC2

    I did a search on those terms, and came up with this thread:

    Deleting the various plist files, as per advice in that thread, didn't help. Nor did repairing permissions.

    The culprit is connected via USB. Try disconnecting your devices, one at time, and see which one is doing it. (Be sure to check your USB device tree in System Profiler for any devices you may have missed)

    That was it, sort of.

    Any devices plugged into my USB ports that were ALSO attached to the "master" outlets on my APC UPS (namely, my speakers and display) were causing the problem. Once I disabled the "master" function on my UPS, the system sleeps.
