No power management but USB devices can suspend or be suspended. Could  
I be coming up in a state that looks like I am suspended? I was  
looking through the changes in git and made the guess that this could  
be the problem since that is where EAGAIN is returned in new ways.

My set of drivers share source; I can rip out a small subset of calls  
and see if the problem reproduces. I will work on getting you  
something nice and tidy to look at.

Thanks for everything.
