Re: [Libusb-win32-devel] Antwort: 64-bit support

[Paarvai N. <ope...@gm...>]

Hi Sprio,

I think what Graeme probably meant to say was that Microsoft allows
drivers to be self-signed as opposed to being self-signed and then
also signed by Microsoft.  Thank you for clarifying that since it is
definitely an important distinction.

The interesting question that remains is whether the INF file needs to
be signed to actually allow the driver to install and load.  Do you
know anything about this?

Best regards,
Paarvai
