Just to confirm, are you certain that the driver in question really  
does work when it is running on baremetal or some other  
virtualization? I.e. this problem really is Xen related, and not a  
problem with the driver, OS, or device itself?
I'm just guessing here, but does dmesg/journalctl have anything to say  
on the Dom0 side? In particular, an error about the driver attempting  
to write to read-only configuration space could indicate that you need  
the "permissive=1" flag. See
