RE: iPad and external DACs

Posted by Gordon Rankin on August 17, 2012 at 08:46:59:
SC,

In the enumeration process the connecting unit tells the host computer how much current it draws. So not matter what you are doing the problem will exist because the iPad is seeing that the device draws X amount of current and if X > max limit then the iPad sends the shut down command and ignores the connection.

The only way is to put a smart powered hub in front of it so the iPad see's that the unit is not drawing any current directly.

Thanks
Gordon
