I don't have enough time for it for the time being. I hope I can post it until the next xen release. If someone want to work for it, I'm okay with that. > I'm afraid i can't code that well, but i still wonder if some bits=20 could be shared with the usb over ip project=20 (http://usbip.sourceforge.net/#about). > Where the (tcp/)ip could be swapped for a more xen specific transport=20 protocol if required. It has had it ups and downs in development=20 activity and I haven't used it for a long time, and it's in staging tree=20 of mainline kernel for a while now. Internal of the Pvusb and the usbip are very different except for the point that they use usb drivers interface. I don't think it's good idea to share the code.
