Hi Juergen, All.

I would like to apply PVUSB drivers for using in our platform while PVUSB
stuff doesn't reach upstream.

Unfortunately, I couldn't find more recent version of "kernel based"
backend driver in mailing list.
I have found it in v0 only.

[Xen-devel] [PATCH 0/4] xen, usb: support pvUSB drivers
<http://lists.xenproject.org/archives/html/xen-devel/2015-02/msg03245.html>

Can I use this frontend driver (v4) together with kernel based backend
driver (v0)?
Are they fully compatible with each other?

Thank you.
