This is already the second similar part I (OTG-capable Android 4.4.2) tried my Odys Tablets and immediately thereafter gekloppt in the bin: It is not possible to load the tablet and simultaneously access a connected USB device (regardless of whether the batch mode or OTG), nor can you have more than one USB device (in OTG mode) operate simultaneously. In three inserted USB sticks you can initially access only the first inserted, after switching from OTG to batch and back requires a reboot, so ever again what is going ... It gets such a part and I dare to predict that the function of these scrap corresponds.
