In Windows 7, Power Options->USB Settings->USB selective suspend setting, what does "USB selective suspend" mean?  Also, given that there is only one setting, why does it say "USB Settings" instead of "USB Setting"?

A USB device driver can send a message to windows telling it to idle the device.  This puts the device in a low-power state (the suspend state).  When a USB device is suspended, windows does not wait for it to respond before entering a sleep or hibernate mode.  If you disable this feature, the system will simply return a failure to the driver when the driver attempts to enter suspend state.  If the driver complies with Microsoft guidelines, it will simply retry the idle request at every expiration of its idle timer.

    The whole reason why google works is because these websites provide information. If there wasn't an answer, "Googling it" wouldn't be an option you <Removed>

    Google is your friend:

    http://www.google.com/search?q=usb+selective+suspend&ie=UTF-8

    Funny that this article is the top entry in google.  In other words, this article would not be on google if the OP didn't ask this guestion.  Therefore, this comment is now invalid.

    For some reason, this thought made me chuckle.

    The irony being that this page is now the top result for a Google search of "usb selective suspend". Quite the paradox you're trying to create there :)
