[Qemu-devel] [PATCH 4/4] usb-host: raise libusbx minimum version to 1.0.13

[Gerd Hoffmann <kraxel@redhat.com>]

Allows to remove one FIXME.  Makes LIBUSB_LOG_LEVEL_WARNING build errors
go away.  And starting with that version libusb has a LIBUSBX_API_VERSION
define which allows to easily #ifdef version dependencies should that
need arrive in the future.
