Thanks.

Hello ,

1. Jetson AGX Xavier of Nvidia is supporting by Nvidia directly. Please kindly contact Nvidia with specified questions. 

2.  CH341 not supporting by Ez-PD configuration Utility is normal case. Since the I2C master on USB bridge shall be decode USB data package and transfer to I2C command as per CCGx specification. CH341 shall be customized to support it. 

Best Regards,

Lisa
