Down table with RC which is support/partially support or do not support (at current moment) work via VCP connection.
| Manufacturer | Typical Firmware | VCP Support | Notes |
|---|---|---|---|
| RadioMaster / Jumper | EdgeTX / OpenTX | Yes | Almost all models (TX16S, Boxer, Zorro) support this natively. |
| TBS (Team BlackSheep) | FreedomTX | Yes | The Tango 2 and Mambo support VCP for Agent M/X and firmware updates. |
| FrSky | ETHOS / FrOS | Partial | Newer ETHOS radios have high-speed serial modes, but older proprietary firmware often restricted USB to storage or joystick only. |
| Spektrum / Futaba | Proprietary | No | Most “traditional” brands use USB strictly for simulators or firmware updates via a dedicated desktop app, not as a generic VCP. |
| FlySky | Proprietary / EdgeTX | Varies | Basic models (i6) do not; newer models (EL18, PL18) or those running EdgeTX do. |
