Razer stream controller utilizes the Loupedeck GUI in Windows, rebranded with the Razer logo, it also has a different ID so that Razer software can differentiate them from the hardware when incorporating them into the "Razerverse". In terms of hardware, I imagine they are not very different the Loupedeck models in terms of communication. Would it be too much work to include support for the two rebranded models?
