I have bought a AppleTV and a Mini White HDMI to AV CVBS Video Converter Adapter 1080P KIT so that I can use my AppleTV with my older non-HDMI television. This is what I bought:

As you can see in the pictures it requires power from a mini USB cable. I have a mains to usb plug that I can power it with but I was wondering if I could instead hook up the 2 devices with a mini usb to mini usb cable so that the convertor would get its power from the AppleTV. Would that work? Or would it fry the AppleTV and maybe both devices or would the AppleTV just not supply power at all out of its mini usb port. I know it is only intended for maintenance with iTunes.


I have found mini to mini usb cables on ebay:

So what do you reckon?

AppleTV 2, Mac OS X (10.6.8)

    I honestly don't know, but I suspect AppleTV does not have a powered USB port and is more like a peripheral (eg ext 2.5" USB drive) that draws power from a computer or hub.


    Another potential problem is that ages ago I read that due to the very close proximity of USB and HDMI sockets it may not be physically possible to have both connected at the same time.
