Usb power on Usb

Hello,

I’m using a Jetson Xavier NX with JetPack 32.7.4 and I’m trying to optimize USB power consumption for better battery life. Is it possible to disable USB device power-up in the devicetree or via the kernel command line, and then enable it as needed from the user space?

Thanks,
Yannick

Hi,
It is related to the hardware design. Is it NV devkit or custom board?

Hello,.
So it’s not possible to disable the power on USB in the device tree or boot séquence and enable it on user Space ?

Thanks
