    All rear USB Ports sometimes stop working...


    And it happens only when I boot the computer up and find that neither my keyboard or mouse are working then I plug them into front (2) avaialable usb ports and they work fine....

    And then If I try to uninstall universal bus controllers by device manager then my keyboard + mouse stops working (obviously) then I shutdown via power button .... plug keyboard+mouse again back to rear usb ports... and they start working till few days...

    I'm on windows 8.1 x64 with latest updates and all latest drivers etc...

    The funny thing is this problem is with me since last 2 years or so... and I changed 3 Power supplies since then and luckily one motherboard, changed 3 mouses and 1 keyboard, 1 Hard disk too

    So what's the problem ? even if they are plugged in rear ports I get "USB Disconnection" sound sometimes....

    I'm sick with this issue, now thinking about buying a bluetooth keyboard + mouse but there are other things that needed to be plug in into rear ports... or should I go for an internal USB 2.0 PCI card ?

    Check My system specs Please.....

    What about your Power Options, power saving plan. Maybe set too aggressive ?

    Control Panel / Power options / Balanced / Change advanced Power Settings / USB Settings to Disabled. Restart computer and see what happens.
    For just mouse and keyboard, go to device manager and Mouse or /and keyboard find Power Management for those devices and uncheck " Allow computer to turn off this device to save power"

    Tried the setting you suggested , lets wait and see what happens in few days....

    about mouse keyboard power management tabs - the checkboxes are greyed out ... I think it's because of the first setting I changed...

    Thanks

    The problem was back this morning...... I disabled faster start up and it went away... I think somehow windows fails to load rear usb ports drivers in fast startup (sometimes) if you google this you will find many people with this issue...

    I don't know if it's a bug in windows 8 for old mobos ?

    I will wait for few more days and update this thread... and may mark this as solved ..

    Thanks...
