[AC Question]

I recently bought an Inateck OTG hub 7-port for my Motorola moto g (2013).
When i plug it in nothing happens, the power light comes on on the OTG hub but the phone doesn't recognize it. I also tried it in my Tesco Hudl 2 and that doesn't work either. In the storage settings they both say that they can connect to an OTG hub.
I also downloaded a File Manager from google play and that doesn't recognize it either.
I'm not sure whether i need to root the devices (and if i do could you tell me how) or whether I've just bought the wrong hub. But i hope it isn't the hub because i spent £15 on it. If you could help with this problem that would be great. Thank you.

The phone doesn't "announce" the presence of an OTG cable. If it's there, and you plug in a USB mouse, keyboard or memory stick, THAT should be recognized.
