I recently let my Hackintosh fall asleep overnight on the Windows side. Once it woke up, I got a continual error message: "Power Surge On Hub Port", saying that "A USB device has exceeded the powers limits of its hub port." I had been running this system fine for weeks until this point; no devices had been added or removed since I got it running. The only thing that changed was I let the computer fall asleep overnight (first time I ever did this). To solve the problem, I unplugged all my USB devices and got nothing. I then simply uninstalled the driver and reinstalled it from Intel; the problem resolved itself: I didn't get the message again. I booted to Mac and got the "Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled." Again, I unplugged everything to avail. During the process, I got a random kernal panic that hasn't repeated itself, and the Windows side of the Hackintosh screwed up again. My best guess is that this correlates to the USB drivers being corrupted or something similar, as reinstalling the Windows ones worked, but I don't know how to reinstall them for Mac. I did a reinstall of Multibeast (without a full format), and got no results. Short of simply turning off notifications, I'd like to know what causes this. A couple questions: 1) Are the USB drivers corrupted? And why would they be? If so, how can I reinstall them for Mac? 2) Would Sleep mode be the culprit? If so, how? It's fallen asleep before, but only for a few seconds at most. Here's what I've tried to fix the problem: 1) Quickly shutting down and restarting: ineffective. 2) Unplugging all USB devices: ineffective. 3) Unplugging USB connectors from the motherboard: ineffective. 4) Booting to Safe Mode: ineffective. Any input would be welcome! Specs are in my signature. As of now the Mac notifications cause constant interruptions that are hindering my workflow to the point where the computer is not usable for any length of time.
