I'm trying to connect my SoftStep 1 to my iPad mini 2 via the CCK. I'm using a powered hub to which I also have a USB mic connected. The SoftStep powers up when I connect it to the hub. When I connect the hub to the iPad via CCK the SoftStep seems to reboot, the activity led at the hub lights up for a second or so then goes off. There is no error message on the iPad. The SoftStep is just not recognized by any CoreMidi apps.
I don't have the current firmware installed on the SoftStep, because I haven't seen any information about possible changes in the hardware midi implementation (switching between hosted and standalone mode, display control, led control). On the iPad is ios 8.
Some further info:
"Have you tried turning it off and on again?" - yes
"Connected it without the USB mic?" - yes
"Tried a differenct USB cable?" - yes
"Tried a different USB midi controller with the same setup?" - yes, and it works with my LPD8
"Tried connecting the SoftStep directly without the hub?" - yes
"Tried a million different sequences of connecting devices?" - yes
"Does the SoftStep work with my desktop Mac?" - yes
Thanks in advance for other suggestions,
