The original Apogee ONE for Mac was USB audio compliant and could be made to work with the iPad with the iPad camera connector and a powered USB hub (see video).
I just tried the the same thing with the new Apogee ONE for iPad. It is USB audio compliant and does work natively with its own cable to the iPad, but I couldn’t get it to work with the USB cable through a powered hub in the same way as the original ONE.
Has anybody else managed to get it to work?
