Just as a matter of trying to understand USB under FreeBSD: 

How did this become broken after it was corrected in 7.3?

The quirk prevents the conflict between hid and ugen (which occurred in 7.1), Why can't 8.1 recognize the device?

Sorry for the multiple questions, I'm just trying to understand what's happening under the hood so I'm better prepared to debug on my own in the future. I have a modest understanding of udev under linux creating the /dev node when the device enumerates, I'm just trying to put together that level of knowledge for FreeBSD as well.

Thank you so much for your replies Hans!
