Anand, do you have any other test-case in mind that we need to check? I CC'ed Emiliano because he initially added USB support to meson8b-odroidc1.dts (that was before I got my own Odroid-C1+). He can probably help us test on his board(s) as well. > Honestly I am using power supply from dc jack rather than power via usb otg. I don't have a plug which matches the little DC jack so I'm powering my board using the micro USB connector.
