Since Microsoft seem to have at least shifted their policy to
allow companies other than themselves to sign drivers ("Self-Signing"),
this seems more feasible that it once was, but it's still
a significant barrier to non-commercial developers.

Is there any distinction between how unsigned .sys and
unsigned .inf files are handled ?

As I understand it, the administrator simply cannot load an
unsigned .sys file, unless the operating system has
been booted up with some special flags that permit this.

Does anyone know if the same apply to .inf files, or is it
merely that the administrator will get an warning/OK dialog for
an unsigned .inf file ?

If not, then there seems less point in continuing to develop
a winusb.sys version of libusb-win32.
