I have an iPad that I would like to leave semi-permanently connected to a USB hub (connected to a couple of MIDI controllers and some USB speakers). As it stands, I have to remember to unplug it periodically and plug in the charging cable.
I've been looking for a solution that would let me keep the iPad charged while also keeping it connected. Thinking about it, I realized I don't know if this something supported by the USB standard (let alone by the iPad specifically).
Is it even possible to charge an iPad while it's acting as a USB host?
