hello @sonyan11, what's the image version you're using? if it's not on the list then the function might not have been added -- my bad. i have updated my previous post with versions that support usb vbus control. for debian 10 kernel 4.4, please use v.2.0.20 or later

hello @nishi and @Thinh Nguyen, you can control the vbus power through echo commands 1. check the kernel version with command: uname -a keep in mind that if you're using a usb keyboard, the power will be off immediately after you execute the echo off command. if you wish to turn it back on without reboot, please: 1. use a type c keyboard, or 2. connect tinker board to a pc with a ttys dongle so the commands can be executed from the putty console here are the commands to control the vbus power: linux4.4 debian10 (v.2.0.20 2023/07/13 and later): TypeA port: echo on > /sys/kernel/debug/fe900000.dwc3/vbus echo off > /sys/kernel/debug/fe900000.dwc3/vbus TypeC port: echo on > /sys/kernel/debug/fe800000.dwc3/vbus echo off > /sys/kernel/debug/fe800000.dwc3/vbus linux4.19 debian10 (v.2.1.16 2023/07/14 and later): TypeA port: echo on > /sys/kernel/debug/fe900000.dwc3/vbus echo off > /sys/kernel/debug/fe900000.dwc3/vbus TypeC port (for cc chip fusb302): echo on > /sys/kernel/debug/fe800000.dwc3/vbus echo off > /sys/kernel/debug/fe800000.dwc3/vbus TypeC port (for cc chip rt1715): echo sink >/sys/class/typec/port0/port_type echo dual >/sys/class/typec/port0/port_type linux5.10 debian11 (v.3.0.6 2023/07/31 and later): typeA port: echo on > /sys/kernel/debug/usb/fe900000.usb/hub_vbus echo off > /sys/kernel/debug/usb/fe900000.usb/hub_vbus TypeC port (both fusb302 & rt1715 use the same commands): echo sink >/sys/class/typec/port0/port_type echo dual >/sys/class/typec/port0/port_type android12 (v.3.0.2 2023/07/13 and later): typeA port: echo on > /sys/kernel/debug/fe900000.dwc3/hub_vbus echo off > /sys/kernel/debug/fe900000.dwc3/hub_vbus typeC port (for cc chip fusb302): echo on > /sys/kernel/debug/fe800000.dwc3/hub_vbus echo off > /sys/kernel/debug/fe800000.dwc3/hub_vbus TypeC port (for cc chip rt1715): echo sink >/sys/class/typec/port0/port_type echo dual >/sys/class/typec/port0/port_type
