MbedWrapper Endpoint issues

Hello!

I downloaded the mbedWrapper android app, but it crashes in the initialization.

When running without the acessory, it crashes in the following line "mManager.requestPermission(accessoryList[0], mPermissionIntent);" Returning a NullPointer Exception, once the accessoryList is null. MAKES SENSE!

The mbed attached to the serial computer tells me the following when I start with the Android device already connected:

Android Development Kit: start Welcome to adkTerm

USB INIT (Controller is 1396 bytes) HubStatusChange Hub:0 Port:1 00010101 ResetPort Hub:0 Port:1 HubStatusChange Hub:0 Port:1 00100103 Connect Hub:0 Port:1 full Waiting Waiting before ep=20000400,callback=00000000 ep=0,callback=00000000 Waiting Waiting Waiting before ep=20000400,callback=00000000 ep=0,callback=00000000 Waiting

Then when I disconnect the device it prints:

HProcessDoneQueue status 00 5 ucessDoneQueue status 00 5 00030100 Disconnect Hub:0 Port:1 DATA SENT

RETRY ADD DEVICE

Disconnect Hub:0 Port:1 ResetPort Hub:0 Port:1 HubStatusChange Hub:0 Port:1 00010100 Disconnect Hub:0 Port:1

As far as I see, looks like the mbed side is fine, just waiting for the device.

UPDATE:

After some tries, now I am getting this from mbed:

Any thoughts?
