Hi, Cosimo from Italy. I have a Mi-One S with Miui Rom. First I tried to connect a pendrive with this cable Micro USB Host OTG Cable and Host Mode works. Second I tried to connect a standard USB DAC (Stoner Acoustics UD100) reportedly interworking with the many Android-powered devices (like Samsung Galaxy S III) http://forum.lowyat.net/topic/2222840/all and does not work. I think USB audio is not enabled via Miui firmware/kernel. Can you confirm it to me? Thanks, Cosimo.
