I want to power some kind of smart home system from the USB ports of the CCGX. Since nothing will take 48V directly, and other things have a standby current, this seems like an efficient way to do it for an offgrid system.
What is the maximum current in mA that can be drawn from the USB ports? And does it need to negotiate USB power correctly, or can I cut open a USB cable and use just the voltage wires directly?
