My Device Manager is showing 21 different USB port controllers See linked 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

it will not make any difference deleting them or leaving them there power is supplied by a PSU it will not drain any power leave it alone or delete them if you feel like it but it will not make any difference
