Open the device manager (Control Panel => Device Manager)

Scroll down until you see ‘Universal serial bus controllers”. Expand it.

Here is the list of all USB hubs inside and connected to your PC. Since their names are all the same we will have to find the hubs that doesn’t deliver 500mA. Double click on every USB hub and go to the Power tab, if it says ‘500mA’ it’ probably not the keyboard. If it says “100mA”. It will probably be your keyboard. this is what mine looked like :

So we found our keyboard, now we need to get the Location Information, go to the details tab and in the property drop down box, select “Location Information”

right-click on the item and select copy. Now open the registry and force windows to put out 500mA to this device. Open the run command (Windows + R), type “regedit” and press OK.

Click on the computer in the top left bar, now hit CTRL+F and paste your location information we copied earlier, hit “Find Next”

This may take a while. When windows found something, it probably isn’t the right folder yet. keep searching until you see a folder “000000000” on the left containing sub-folders (Control, Device Parameter, LogConf, Properties) (mine was in HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\USB\VID_05AC&PID_1006\000000000000/)

right-click on the “00000000000” folder and select Permissions. A new window with Groups and User Names will open. select usergroup “Everyone” in the top section and tick “allow all” in the lower part, now hit “Advanced”.

A new window will open. click the “Owner” tab and check the check box at the bottom “Replace owner on subcontainers and objects”

now hit OK, and OK again, an error will pop up, hit OK again.

Now we are owners of these folders, click the “DeviceDesc”.  Clear the line and type ”Apple Keyboard” and hit OK. This will change the name from “Generic USB Hub” to “Apple Keyboard”.

Go back to your Device Manager, click action and “scan for hardware changes”. In the list with “Universal Serial Bus Controllers” one of the “Generic USB hubs” should have changed to “Apple Keyboard” (If not, reboot your PC). Just to be sure you are editing the right hub, unplug your keyboard and check if the “Apple Keyboard” disappeared. also check the power tab again if it still says “100mA”.

If you are 100% sure it is the Apple Keyboard, go back to the “regedit” window. Click the subfolder “Device Paramaters” (dont expand the folder, just click the folder not the arrow in front of it!) It should have 2 parameters(Default and SymbolicName).

Now right-click in an empty part of the right screen and select “NEW DWORD(32bit) VALUE”. Name it “ForcePortPower”. Double-click on it, set the base to “Decimal” and enter the number “500” which is the amount of mA (!!!Never enter more than 500!!!). Hit OK and your folder should look like this :

Close the regedit window and unplug your keyboard. Wait a few seconds and plug it back in. Check the “Power” tab again in the Device Manager and it should say the hub is “Self-Powered” and the “Total Power Available” should be 500mA. (If not, reboot your PC)

Your keyboard should now be able to run any USB Stick and even USB powered HDD’s.
