    Is there any way to force the macbook pro to feed the additional 500mA to a usb plug? I know the iPhone triggers the extra 500mA bringing up the total to 1000mA but all other devices don't have that ability.

    My PS Vita draws so much power it requires to recharge while it is off via the USB plug. Even then it takes forever. Is it possible to force it so that the computer charges it at 1000mA?

    No, you can't force the capabilities of the USB port to change.

    Do you need it connected to USB? Is plugging to a 1000mA wall charger not an option?

    "Forcing" your MBP to deliver more current is a sure fire way of burning out the ports, even your logic board...Use the proper charger.

    The macbook pro is designed to supply 1000mA. These newer laptops were designed for rapid iPhone/iPad recharging. However, they only go into that mode when a iPhone or iPad is detected. The computer does not charge other electronics at that rate.

    I was wondering if there were some applications that would trick the laptop into thinking the Vita or whatever usb device was an iPhone/iPad.
