I’m sorry if my response came off the wrong way. I just wanted to say
that it is not completely accurate to say that each driver signature is
locked in to one specific OS only, and that it is always necessary to
run the DTM tests on every platform that I want to support, as the
response would suggest. For example, if one is not interested in the
logo, but only the signature, it will be sufficient to pay for an XP
submission only, and its signature will still be accepted on all other OSes.
Again, I apologize for any misunderstandings if the response meant
something else.
Of course, I’m perfectly willing to accept that we may have to do an XP
submission in our case. I just don’t want to pay for an extra OS in the
submission if it is not absolutely necessary.

Since you don’t like the response you’ve been given, I suggest you
submit the driver with the DTM results you currently have. When it
comes back and you find it isn’t signed for XP, then you can run the DTM
for the XP tests and resubmit.
I’m sure your company won’t mind the delay and the expense.
Mark.
