Hi

I have got 4 cameras connecting to the Jetson Xavier Development Kit via the x2 USB-C connectors, and would like to disable USB VBUS until it is needed.

Noticing that the Cypress CYPD4226 have the capability to VBUS_P_CTRL and VBUS_C_CTRL, I assume the processor can control these lines via the I2C lines connecting to the CYPD4226. Could you share some lights into how how I can interface to the CYPD4226 and control the USB bus via the I2C interface?

Thanks

Thomas

VBUS_P_CTRL and VBUS_C_CTRL is controlled by CYPD4226 FW, it can not controlled by Tegra I2C interface directly.
