_usb_khci_task_create() does not return

I have used KDS/KSDK/PE/MQX to set up a simple USB host application for a FRDM-K22F board. My problem is that when the _usb_khci_task_create() routine is called, it does not return. Instead something goes awry and I get a "<signal handler called>() at 0xfffffffd".

 

I have tried single stepping through the process, but am now knowledgeable about the Kernel to understand what's happening.

 

Any pointers welcome.
