I'll bite. I've got a 2.5" HDD with an enclosure that connects via regular USB 2.0 making it "portable".
No luck. No LED. It's simply not receiving enough power. I have a hunch that if it were powered by from the mains and
the HDD plugged in as well, then it would maybe work, but there's only one thingy, and IDK if it would be powered via a hub without the hub melting. xD
I did, however, try a 1GB "pendrive" which worked just fine via the OTG cable. I'm certain larger sized pen
drives would work. You can get some cool things. I'm pretty sure there's Micro USB pendrives, but there's also this which would greatly reduce the luggage:
I'm not sure if this is truly Micro USB, but it looks like it might be. Would be amazing.http://www.ebay.co.uk/itm/KINGSTON-32GB ... 1588933439
OMG, this is!http://www.amazon.co.uk/Transcend-JetFl ... ICRO+USB+2
Awesome stuff. Think I might look into one, myself.
