# HG changeset patch
# User kaf24@xxxxxxxxxxxxxxxxxxxx
# Node ID e2a2b2da92f471b9cd8674f776ddd3b6f28042cf
# Parent 5b1bd9eab3b9a715543937f3d9a083faa23f0f53
[HVM][DM] Backport the USB support from QEMU 0.8.1 to the current Xen
device model. To support USB there are two new optional config lines
that can be added to the guest config file:
usb=1
This will enable USB without defining a specific USB device.
This option is assumed and not needed if the `usbdevice' option
is given.
usbdevice='device'
This will enable USB and also enable support for the given device.
Currently, the only two devices are `mouse' (a PS/2 mouse) and
`tablet' (an absolute pointing device). The advantage of `tablet'
is that Windows guests will automatically recognize and support this
device so specifying the config line:
usbdevice='tablet'
will create a mouse that works transparently with Windows guests
under VNC. (Linux doesn't recognize the USB tablet yet so Linux
guests under VNC will still need the Summagraphics emulation.)
