Anyway, I ordered a USB otg cable for my Asus Memo Pad HD 7. But I ordered one with a third plug to supply power to the mouse/keybaord/usb drive, as I read it needed that. And mice/keyboards work great! No rooting is required, just "plug and play"! But USB drives don't show up (there's even a folder called usbotg) and I'm not sure why. If they simply need mounting, is there an app for it? I'd rather not root right now since I just replaced a hard bricked tablet and that's never fun. Thanks!
