Any way to use USB as host data and charge at the same time?

[tjcorcoran]

I need to have a Mediatab M3 connected to some hardware via USB in a kiosk setup running 24x7. I can't seem to figure out how to also charge the tablet through the same USB connection. Does anyone know if it's possible to charge while also using USB to receive data from some hardware? All of the adapters I've found seem to only work with charging the peripheral and not the tablet.

Thank you!
