I have a few devices with no public drivers of any kind. Thinking about how to develop drivers on Linux, I’m guessing I should lookup into the chipsets used on the board and see if those companies have drivers I can use as a starting point?

Does it have Windows drivers? If it does, you can set up a VM, set the device as passthrough, and sniff the traffic to it. Then it's not really any different than reverse engineering a network protocol or file format.

What are they, out of curiosity?
