Tried the OTG cable i use on my Nexus 7, but all i get is 'USB storage blank or has unsupported file format'. Using a 16Gb USB key that works fine on my 7. Finish for the holidays tonight (woohoo) so will hoepfully have time to have a play around properly tomorrow.
Do you need one of the OTG helper apps: https://play.google.com/store/apps/...t=W251bGwsMSwyLDEsIm5ldC5zaGFqdWwudXNib3RnIl0.
I've not tried an external drive on my N7, but I know without root, it works with both my Xbox and Sixaxis controller.
Enjoy your holidays!
