Not all USB A to USB B mini adapters are OTG. The worst thing is a lot of resellers have no clue. I have bought a bunch of advertised OTG adapters that weren't and some that weren't listed OTG that were.thanks for the post and the link to the other supernova thread, it'll come handy. I saw one comment saying about this amazon's adapter http://www.amazon.co...11187567&sr=8-1 but other person refuted it and said it didn't work with his devices. Just wondering because that would be easier than getting a USB Female coupler to connect the USB cable that comes with the PDSN8 and let's say a USB keyboard.
