wired to a pc. for a year i wondered what prevented multiple displays on multiple computers from auto powering down. or the screensaver. it will constantly randomly wake back up. i finally figured out what it is. do you think the controller is a defective one or a known problem with it? or perhaps something with microsofts software. that is all that is loaded, the driver. i could get another but i will be miffed if it is the same issue. i googled this and nothing came up. nonethelsss, i am happy i finally figured it out. for a long time i blamed it on the poor g500. which it turned out not to be. i was sure it was a usb device though. there is no option to turn off "wake" on the 360 controller like other devices.
