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

>From what I have read the INF does not need to be signed.  I might be
wrong so I want to try this in-house and see what the result is.  The
impression I had was that Microsoft wants to keep the kernel mode code
signing (KMCS) separate from WHQL.  The INF gets signed and hashed as
part of the WHQL process.  The links I posed earlier were:

http://www.microsoft.com/whdc/winlogo/drvsign/kmsigning.mspx
http://download.microsoft.com/download/9/c/5/9c5b2167-8017-4bae-9fde-d599bac8184a/kmsigning.doc

There is discussion in the kmsigning.doc that specifically says that
you can release a driver *without* WHQL as long as you follow KMCS.
And then, there is discussion on KMCS and how it only requires that
the KMOD be signed, its hash placed in the CAT file, and the CAT file
signed.

Sprio, did you look through that document above and find something
contradictory, or are you working of some other reference?
Personally, I'm unclear on all of this and Microsoft's documentation
hasn't been the greatest here.  Sadly, the only way to really be sure
would be to try this all out or here from someone who has.
