Yeah, I tend to agree.

Sure. Note that linus/next is having even more issues with this device,
to the point where I couldn't even get the lsusb I pasted into the first
email. I used 3.13 (because I had it installed on the system in
question) to get that.

It was also throwing an autosuspend warning:
http://mid.gmane.org/1402177014.8442.1.camel@xxxxxxxxxxxxxxxxxxxxx

I'll try to get some logs (wasn't there tracing added to xhci too? will
check)
