    How to change registry keys to increase USB power to 500mA?


    First of all I confirm that in my case only the generic Standard USB drivers work. Intel drivers fail to properly detect any device plugged ("unknown USB device" error), except perhaps a USB mouse! To do that right-click on a USB device (not the USB Root Hub devices, the controller devices) and select "Properties". Then select "Update driver software". Select the last option, then again the last option. You should see a list of compatible devices. The last in the list should be the generic "Standard PCI to USB controller" (or Enhanced controller for the USB 2.0 device). Select that and proceed to install it. Windows might warn you they cannot verify compatibility etc. Ignore this warning and proceed. Replace all USB controller devices and then restart your system. USB ports now should work better. As said before, in my test server system this is the only way to make my USB ports work! I also have this issue in Linux and Mac OS X. The USB ports don't work properly for some reason. At least they do work in Windows 10 using the standard drivers. Thanks God!

    I don't recall changing the USB driver. Follow the video but keep in mind the video was for Windows 7 not Windows 10. I my post above I describe the differences between the two. Make sure you have the correct USB port address to change power on.

    In my case wasn't a power problem but a driver problem as it seems. None USB port worked no matter what device I tried. It only works properly by replacing the Intel specific USB controller drivers with the standard (universal) USB controller drivers.

    That's interesting. All I did was follow the Dailymotion video & changed the allotted power to the port. Changing driver would probably be best!
