USB power source identification and control
To explain, let's first go back to the basics.
Most of the communication between a portable device (PD) and a USB power source relies on the D+ and D- lines of the USB connection. Of course those USB data lines were not designed for signalling but for data transmission in a differential way: D- going down when D+ goes up (and conversely) and the receiving device subtracting D- from D+, so that if noise or spurious peaks happen during the transfer, they appear on both lines and the subtraction cancels them. But as a charger does not use the data lines, several standards or proprietary protocols were designed using those wires in a primitive way to identify the source or control it.
The first convention is that a charger starts with D+ and D- connected together (shorted), which is incompatible with the differential mode, and can thus be detected. If a PD is QC-compliant, it will set a voltage of around 0.6V on D+ for around 1.25s. If the USB power source is also QC-compliant, it will detect that voltage, remove the short between D+ and D- and connect a 20K pull-down between D- and GND. That is the QC handshake phase.
After that, the USB power source will start monitoring the voltages on D+ and D- and will act according to the detected levels.
You want to start here:Hey everyone! My cousin just moved and her and her boyfriend got a 2020 CX5 base model. Where do I find the firmware needed to get her Carplay? Is there anything specific I need to know and/or do? Any other updates needed in the system first? I already found the hardware to order...
Thanks!
What version of Mazda Infotainment are you running?Lately I've been having connectivity problems with CarPlay. One thing happens where I plug in the phone and CarPlay doesn't activate. Another is Spotify resumes but no audio. Various glitches lately. Is there a Mazda infotainment update?

I'm guessing you mistook his comment to mean the vehicle's lights? It should, for sure, be able to turn on your house lights, or anything else that's programed in the app....
B) It wouldn't be able to turn your lights on.
