    Device manager showing numerous usb controllers do I need them all?


    My Device Manager is showing 21 different USB port controllers See attached screen shot
    I suspect some are from old USB devices once installed that I no longer use.


    Can these listed USB controllers be causing a drain on the power needed to operate USB ports?
    Is there any way to see if these controllers are redundant or actually still used?
    Thanks for your help

    Hi,
    Looks normal to me but you have more feature than I do
    If you want them to work then no don't remove them
    One control and one hub for each usb2... port

    Leave them as it is :) Devices that are using USB Controllers will be there.

    Yes leave them alone. It's possible that some of those entries are for USB devices that are no longer plugged in and could be cleaned up but it doesn't cause any problem to leave those entries alone.
