    USB Ports Not Providing Enough Power For Peripherals?


    I have a custom built PC and a long time ago my mouse died. I thought it was due to the mouse just being faulty but I tried it with another PC and it worked perfectly. I was confused and tried the mouse in the bios settings of my computer and it worked perfectly again. However when I booted into Windows, the lights on the mouse went out and Windows didn't even pick up that a mouse was connected. I also noticed that certain USB memory drives and external hard drives were very temperamental when it came to functioning properly with certain USB ports, it just seemed to be random whether they decided to work or even be recognised by Windows. This was usually fixed by unplugging and plugging them back in or trying a different port. I sort of ruled out a motherboard or port issue as the ports that didn't work were always different, and it was all very random.

    The mouse however, didn't work at all regardless of which port it was plugged into. I managed to come up with one fix though, my keyboard has one USB passthrough which when I plugged the mouse into, worked perfectly again and so I used that for a few months as a temporary fix. The external memory problem wasn't fixed though.

    Then today the keyboard died too, it is fully back light and it just went out following an update of Windows. Neither the passthrough nor the keyboard itself work at all and are as if they are both unplugged. They are not even recognised in Windows. One strange thing however is that when I plug my keyboard into a USB 3.0 port it lights up and the back light works again, and the mouse lights up through the passthrough too but it is still completely infunctional in Windows. One other thing I noticed was that when I initially plug my mouse in to the passthrough it lights up and so I know there is power running through it but immediately goes out unless the keyboard is plugged into a USB 3.0 port. Please note that if the mouse is plugged straight into the USB 3.0 port it doesn't light up at all, only through the passthrough.

    I know I should uninstall the update but as I have no working keyboard or mouse I can't and it would also be a short term solution and I want this completely resolved.
    Any help is greatly appreciated, thank you.

    boot into safe mode and see if things work there. this will eliminate a hardware issue. and point it souly to windows.
    If this works fine, download and install the latest chipset drivers for your mobo, as well as the usb 3 ones as theys are controlled by a different chipset on your mobo. this should solve your issues.

    im starting to think its pointing towards hardware issue, but the fact things are fine in the bios puzzles me.
    do you have a windows 7 disk that you can use to run windows repair? if you do i suggest running it and seeing if that helps the issue.
    Ive done a bit of snooping online and the only other people with similar issues tend to only have luck running repair or doing a complete fresh install of windows.

    I've now realised that it's all USB ports that don't work, but I still believe windows to be the problem as I plugged in a USB drive and it's recognised in the bios but not windows. I'll try reinstalling windows, but how can I do that without a mouse and keyboard? Lol

    Your mouse and keyboard should still work in the BIOS. If so then you're safe to install Windows.

    Do you have another mouse and keyboard you can test?

    All hardware parts should be checked for power consumption.
    For example, even a faulty or replaced graphics card may be the cause.
    That's what was the exact problem in my case, my video card consumed to much power resulting in not enough available for other powered devices.
