Yes, I follow it on gmane.org as gmane.linux.usb.general (not sure what the real name of the mailing list is) and Sarah Sharp is the xhci driver maintainer. She was very helpful and patient when I was having similar and quirky problems with my usb3 adapter, and it did turn out to be a driver bug. And such quirks can be very much device-specific. I would not want Sarah's job, but I'm glad she does :)
