Yes, in order to do anything with a USB device working in gadget mode,
even those that have a dedicated power supply, a modified USB hub is
required.

This hub would provide power to both slaves and master. Usually it's a
matter of shorting the appropriate lines of a slave port and the master
port. And there might be a decoupling capacitor to be removed.

However please note that I'm not to be held responsible for any possible
damage/injury resulting from a bad hw hacking =)
