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.

    HAHA..No kidding! I was thinking the same thing! Obviously he had NO idea what the answer was...And what makes it even more funny is that Google is a SEARCH ENGINE,so all it does is give you links to sites with the answer,and doesn't actually answer anything.You would think it not having a forum would be a big hint! Lmao...

    Replied with this

    • Press Windows Key + X.
    • Select Power Options.
    • Next to your currently selected plan, click Change Plan Settings.
    • Click Change advanced power settings.
    • Click the box to expand USB Settings, then expand USB selective suspend settings.
    • Click the drop down menu and select disabled.

    Had since swap the 200 KB out but am going to swap it back to see if this works
