Wah... totally got the wrong end of the stick :-/  You're asking about
host mode.

Currently the pump that provides 5V for the external device is enabled
whenever we are in host mode.  I don't know what that thing will do if
we provide 5V externally too, probably it will be okay but it needs testing.
