[Xen-devel] [Patch V1 0/3] 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, phono preamp, ...).

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

Juergen Gross (3):
  xen: introduce dummy system device
  xen/usb: add capability for passing through isoc jobs to host devices
  xen: add pvUSB backend
