Is there any way to completely cut off the power of USB? I have Linux on DB 410c.
I tried using the following Linux command which is used to suspend the USB, but I still have an ‘on’ LED on the USB device, and even I can communicate with the USB device.
sudo bash -c ‘echo 0 > /sys/bus/usb/devices/usb1/power/autosuspend_delay_ms;
echo auto > /sys/bus/usb/devices/usb1/power/control’
