USB mass storage with dragonfly

I am attempting to use the Dragonfly:

https://os.mbed.com/platforms/MTS-Dragonfly

as a USB mass storage device using the library:

I find that it does not even get enumerated, so my host does not recognize it. I have no real test gear other than Wireshark. I do see that none of the interrupt routines are being activated, and I don’t know how to even investigate that.

So, I am wondering if anyone who has used the Dragonfly as a USB device has any advice or experience with this combination.
