I wanted to make an app that communicates with MIDI interface accessories for iOS. I bought an MFI licensed device (iConnectMidi), plugged in, and created a simple project that calls [[EAAccessoryManager sharedAccessoryManager] connectedAccessories] after app launch, but was not able to get accessories read in. I was wondering if anyone that has similar experience can shed some light on this?

As par mentioned in the comments above, if you don't specify the protocol string in the plist, the app won't recognize the device. In my case I am using a MFI midi interface, the EAAccessoryManager won't read the device because I don't have any protocol setup for the
UISupportedExternalAccessoryProtocolsfield in the plist file. However, I was able to detect the device using the CoreMidi framework. There's a little sample code I found https://github.com/petegoodliffe/PGMidi, if anyone ever comes to the same confusion I had.
