That would be a 50/50 chance... as it would also have to be a hub, thought I am not sure if Samsung's MHL will allow both USB and HDMI to function simultaneously.
Nice catch on the web... though I do which the Samsung MHL adapter was more secure than just a dongle. MHL connector is very week and the extra weight of the HDMI cable just wants to pull on it.
