If Samsung is using a standard USB-C implementation, I would suggest using Benson Leung's sheet on Google Docs to determine the adapters and cables that will work properly.
There was a device released recently that did NOT have a spec-standard USB-C implementation and in that case the sheet above is somewhat moot. I guess it remains to be seen which way Samsung decided to go, and I'd avoid purchasing any accessories until there is a definitive answer.
