I bought the Official Dell OTG Data and Charging Cable before I read that it would not work. Well it does not work as intended but I do have a use for it. The Dell OTG Data/Charging Cable has actually replaced my other OTG Cables. The Dell stays in the AVTN8 (during an extended session of tablet use) so I would not have to keep plugging things in and out of the tablet. I just plug the charger/USB devices in and out of the Dell Adapter instead, thereby, hopefully preserving the life of the AVTN8 micro USB port.
