How can I determine USB host controller type
I was told i would not have permissions to comment here?!? Therefore here my comment.

Perhaps you could have a look on what additional cables are available for your device. If you want it to be usb master there's a universal cable that works well. But if you want hdmi connection, make sure you take a samsung adapter for your samsung device, the standardized version won't work, samsung has it's own protocol there.
