Did you measure current/voltage output from your home-brew USB thingy? Seems to me if the phone is not getting the required juice, you are out of luck. What are the power requirements for the Evo and what are the specs of the Touchstone inductive charger?
You might have a look here:
Energizer Inductive Charging Pad | Charging Station | Qi Technology
They make lots of stuff for several devices. Perhaps your answer can be found there.
I like the idea of induction charging. Nice to have a way to eliminate those power cords and wall warts.
