That's better... I think you might be hitting the same bug I've been
hitting on my system...

It looks like we're calling devmatch, but it isn't seeing the modules to
load. There's still a mismatch between things in the USB code (likely my
fault, I thought I'd fixed them all: either I missed one or broke
something). Try running with r329538 (it's just a new devmatch, so all you
need to do is install just it).
