This is a very common question. There are a few resources at your disposal
- Read the Microsoft public newsgroups, especially microsoft.public.development.device.drivers
- Search the web, somebody has probably already asked your question
- Ask me 😉 (but please don't email me, keep it public so that others can see the response)
- Join the NTDEV alias which is run by OSR
This list is far from definitive, but does offer a good starting point.
