Interesting.I don't know much about this but as at the same level you are I would have checked first wether the Samsung Galaxy S3 has a USB OTG sw support or not.You can try this by inserting a USB keyboard into it or a Mouse and see whether it is working. I think it has : *USB:*USB 2.0 client, 480Mbit/s micro-USB
What you need is *USB:*USB 2.0 host/client, 480Mbit/s USB A Rgds, -s On Tue, Feb 26, 2013 at 10:50 PM, Marta Ribeiro < [email protected]> wrote: > I'm using a Samsung Galaxy S3,and connecting to a sensor using USB host > and a OTG cable.
