Using the One as an HDD drive/USB stick
Both my Desire & Desire HD had a feature under Settings to set the phone to act as an HDD drive or USB stick to feed the USB port on a TV or car radio etc.
It is probably straightforward but I can't see how to do this on the One.
I have contacted HTC support who have tried to help but, because of the language difficulties in Thailand where I currently am, cannot understand the question.
Can anybody advise?
