Ok, I wasn't going to post this just in case it didn't work for others, but I have now reproduced the result 6 times on my Venue 8 - So someone else try this.... I was hacking some cables testing some theories, and thought I had a working hacked cable - Exciting, Power and USB ... Then I tried again without powering off the tablet and it wouldn't work... I failed.... Or did I? In another attempt I used a standard OTG cable and bang it was working - Power and USB - NO HACKS ... How? Its all in the boot sequence... Try this : 1. Power down tablet 2. Plug JUST power in - wait for the white light 3. Power up the tablet 4. When the Dell Logo starts spinning, unplug the power - plug in your OTG cable and plug the power into the power portion of your OTG Y Cable. 5. You should notice that the light NEVER went Amber during this. 6. When you get to Windows check the Desktop - Should show plugged in 7. Plug in a USB Device - Should work as normal, and have power! (Ive tested with an External mSata and a USB 64GB Thumb Drive) Post your results ... This cant just be dumb luck on my tablet?
