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.
