For a Y-cable device to work, it needs TWO ports. Therefore, by itself, the Rosewill does not work with the Surface Pro as-is. For my use case, I only need an optical drive in the rare occasion I can only access some software (e.g., legacy) via DVD/CD. This, for me, means I only need the optical device at home while docked and, in my case, "docked" means connected to a 10-port USB 3.0 hub. Thus, I have the additional free spare ports needed for the Rosewill's Y-cable; it does not require a power adapter (since it uses two ports).
