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.

    From what  I  have found,  the idea was to save power on laptops.   I  am having a "freeze-up" (mouse) on a desktop !!   So,  I  disabled it......  and will see......   mouse had become frozen on a number of times;  so remembered a setting in the advanced power options menu......  guess will have to wait and see what

    occurs next .....   also on hard drive and the sleep after mode,  i typed in never !!!   That will be the next

    **** to deal with !!

    Hope All find their answers.....

    Hi,

    I am using a DLink DWA-643 Express Card WiFi Adapter in my laptop. Win 7 64-bit can detect the

    hardware and installed the driver.

    But after restart my syste, it cannot detect the adapter. I need to unplug and plug in the adapter again and scan for hardware changes.

    everytime i restart, the adapter is not detected automatically. I need to unplug and plug in again.

    Kindly advice.

     you might be having a "Plug and Play Devices" system service problem. i would check to see that the service is enabled and set to Automatic.
