Hi Eric
Feels like a long time since we last chatted! Hope you are well!!
Since then, I have now moved teams and working as part of the Cloud Foundation Team... so my knowledge of the latest updates around USB and RTAV is limited. Hopefully someone else on that team can provide comment.
That said, RTAV will redirect the device automatically if it is left local on the client side. if you want to redirect using USB then simply redirect it using USB (Rtav doesnt use USB)... but explicitly redirect the device using USB should work.
i dont recall if its possible to rename the device name for the rtav virtual camera - i dont think so. As such usb might be the best option for you
cheers
