Has anyone used a Behringer UCA202 (or UCA222) with an iPad 2? Does it need a powered USB hub to work?
There's a video on the UCA222 product page, but that's clearly a first-generation iPad, which provided way more current through the Camera Kit.
Also, is iPad's internal sound device available when another USB soundcard is being used? I intend to use this setup with Traktor DJ to have proper pre-listening.
