[Spice-devel] [PATCH v7 20/20] test-cd-emu: Test no libusb context support

[Victor Toso]

From: Frediano Ziglio <fziglio at redhat.com>

Although currently not supported by the code (libusb_context in
SpiceUsbBackend is never NULL), try to support it in order to be able to
have only emulated devices if the libusb layer is failing.
