Turning off the USB

Hi
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’

Thanks

Hi @amati,

It would be nice if it is able to cut off the power to the USB connectors.

To cut off the power, it requires the hardware support normally on PMIC, clock generator and power domain design on the PCB.
Current 96Boards CE specification do not mandate to have this hardware implemented, probably to be flexible to have many 96Boards as possible to be made, and not be too strict.

There are many requests on this forum for good idea to improve for the future boards and I am hoping some of idea will be included in on of the future 96Boards.
