[SOLVED] Core in DFU mode fails to enumerate

I have a core, that when plugged in through USB, OS X “fails to enumerate” the USB device…

I can put the core into DFU mode and dfu-util does not find it…

This is the output I see when I plug in the device, before I set the device into DFU mode… Once I put the device into DFU mode, I don’t see any more output in Console and dfu fails to list the device.

3 other devices work fine. Tried swapping out USB cables, did not work…

Thoughts? The core flashes fine OTA and interacts with tinker…
