Well - I just tried my new CCK (lightning) for the first time with my ipad4, and I'm sad to say that it does not work with the Topping tp30 I'm using in my office setup and gives me the "this device uses too much power" error message. This is pretty frustrating for a couple of reasons: (i) the Topping is a self powered device (actually running off a pyramid ps4kx regulated bench ps), and (ii) the Topping has been confirmed to work with android devices. /sigh @ apple.
What powered usb hubs are you guys using to circumvent this issue?
Sometime soon (probably this weekend), I'll also make sure to test, and report back on compatibility with, my blue circle usb transport and jds odac.
