[Question] What is needed to get this working on SB1?

[envyniv]

I would like to contribute to this project in order to get it up and working on the SB1.
Apologies if this has already been asked or if there are clear resources online already available, but I feel like listing them here might help with organization.

Unfortunately this won't work on the SB1 since it's missing the driver stack for the embedded controller.

i'm assuming the dtx platform driver would have to be extended first?
What is needed to that end? Does it require reversing the matching windows drivers?

Does it require reversing the matching windows drivers?

Pretty much. Surface devices have an embedded controller. The way that works and is connected changed between SB1 and SB2, so for SB2 and later we have a working driver for that. For SB1, we would first need to figure out how exactly to talk to the controller.
