Sorry for the delay, I'm currently at FreedomHEC Taiwan with a bad case
of jet lag...
I've attached some of the specs that I received, do they look

We never guarantee any schedule for drivers written using this process,
but vendors usually like drivers "yesterday" :)
I have 2 samples here to test with, if you want to work on this, let me
know and I'll send you one.
