Hello,

On a Raspberry PI 3B+, it's simple to turn power on its four USB ports off and on. Simply write a "0" to /sys/devices/platform/soc/3f980000. usb/buspower to turn power off and a "1" to turn power on.

Is it possible to disconnect power to the USB port on Luckfox Pico Mini A (to reduce power consumption) via software in ubuntu?

Also, is there a breakout for the pico mini USB (so we can expand USB to more ports)?

Hello, our hardware design does not use PMU. It is DC-DC voltage reduction and directly supplies power to the system. It does not support software control of USB power supply

There are no USB-related test points or pin leads on the Luckfox Pico mini.
