[Xen-devel] [PATCH v2 0/2] usb, xen: add pvUSB backend

[Juergen Gross <jgross@xxxxxxxx>]

This series adds a Xen pvUSB backend driver to qemu. USB devices
connected to the host can be passed through to a Xen guest. The
devices are specified via Xenstore. Access to the devices is done
via host-libusb.c

I've tested the backend with various USB devices (memory sticks,
keyboard, ...).

Changes in V2:
- rebased to current qemu master
- removed support for isoc requests in this series, as the optimal way to
  support those isn't clear yet. Will be added in a followup series.
- several changes as requested by Stefano Stabellini and Konrad Wilk

Changes since RFC:
- open device via qdev_device_add(), making patch 1 obsolete
- modify patch 2 to use isoc passthrough via libusb instead of one
  job per frame

  xen: introduce dummy system device
