USB doesn't give you a lot of power. If you want your Remote to be connected, it's going to be hard to find a combo that works with USB power only (if at all). and "works" means works reliably. With such a setup, there is more ethernet cable involved than with just a remote cable. And that again influences the power consumption. The USB port on your Profiler is designed to power an USB stick, maybe a drive but it shouldn't be used for other things. That includes recharging your phone.
It would be interesting to learn the reason(s) why the USB port(s) weren't chosen to add wireless to the legacy models. There must be a practical reason given the fact that USB adapters for Wifi and Bluetooth are easily obtained.
