OK. Time for today's dumb question... I got my OTG dongle today. I'm rooted. Stick a known good flash drive on and I get... ...nothing. Both File Manager HD and ES File Explorer don't show it. The tab doesn't, like, 'do' anything when I plug it in (I mean as in there's no sign it recognizes anything is there). Am I missing something? Should USB debug be on/off? Sacrifice a goat? What? Also, when I say 'known good' I mean I plugged it into my Mac and a Windows 7 laptop and there are a couple of files on it.
