It doesn't work this way I'm afraid.
The OTG port is for firmware upgrade purposes only.
The other mini USB port is for connecting a usb drive (e.g. pendrive) to. Other than wireless that's the only way you can transfer data on/off the unit.
You can also link things like wireless keyboard/mouse combos to it with this port, but definitely not a PC
I know, I know, its bonkers, but there we have it. What can you do??
