Your V700R is badged "Cakewalk" because when Roland owned Cakewalk Roland decided to badge all their interfaces as "Cakewalk". I have a UA-101, an interface which was originally made by Edirol. Roland took over Edirol and rebadged the UA-101 and other interfaces as "Cakewalk".
Cakewalk didn't write or maintain the drivers for the "Cakewalk" badged interfaces. Roland wrote the drivers and they were (and are) downloadable from Roland's website, not Cakewalk's.
Roland then sold Cakewalk to Gibson, but the interfaces and associated software licenses weren't part of the deal. The drivers for the various Roland-made interfaces are downloadable from Roland's website, and which interfaces get driver updates is decided entirely by Roland.
I seriously doubt there's anything Cakewalk can do to force Roland to write drivers for products Roland have decided not to support any more. I also strongly suspect that were Cakewalk to attempt to write and distribute a driver without Roland's consent and authorisation then Roland's lawyers would get very upset indeed amd the courts would be on Roland's side.
