I have an ASRock motherboard and they rebranded this feature as "App charger".
This enables windows to send over 1A through the USB port and I also would like to find a trick to enable it for non apple devices.
The only way I know to charge the non apple devices faster is using a double headed USB cable that comes with some external hard drives boxes. We get 1Ah as it is getting power from two ports.
Regarding the use of this feature on other motherboards, I'm not sure if it is healthy since forcing extra power to USB ports might damage something. My vintage PII laptop sometimes complained about power surges on USB bus when I connected high powered USB devices so probably wont be happy with this.
