Iirc that requires a usb connection at least in the first instance right? I guess only one way to find out if the usb c charging port on the Chromecast dongle supports any kind of data transfer
The last non-AndroidTV Chromecast model was discontinued over 3 years ago. Seems reasonable to assume AndroidTV model, if OP doesn't specify, at this point
The answer is yes it does, this is how I did it. Maybe you can prove me wrong but I don't think I've ever seen a USB-C port that was incapable of data transfer, I actually thought it was part of the standard
