Back feeding a Raspberry Pi from USB bypasses the fuse in the
Pi. It is probably a good idea to include one in the power
supply to the hub. That is how I powered my Pi.
When I changed to a Beaglebone Black, the USB wouldn't work. I
had to remove power to the hub and power it from the Beaglebone
before I could connect USB devices.

In the case of the Raspberry Pi, I have had luck with some powered hubs
being able to back feed 5V on the USB data connection and actually power
the Pi via it's USB dataport. This also may work for your tablet if
luck is with you :)
