Partial rewrite of OpenXT's xc-vusb-daemon

• In your OpenXT OpenEmbedded tree, edit repos/xenclient-oe/recipes-openxt/xenclient/vusb/vusb-daemon_git.bb
  Replace git://${OPENXT_GIT_MIRROR}/xc-vusb-daemon.git
  with git://github.com/jean-edouard/vusb-daemon.git
• Also edit repos/xenclient-oe/recipes-openxt/xenclient/vusb/files/xenclient-vusb.initscript
  Replace PROG=/usr/sbin/vusb_daemon
  with PROG=/usr/sbin/vusb-daemon
• Rebuild using ./bb -c cleansstate vusb-daemon && ./bb vusb-daemon

• Install the resulting package from the previous step.
• Running restorecon -F -R / could be enough, but you may need to just set SELinux to permissive.
• Reboot
• Try passing USB devices to VMs
