Dear TI engineer Hello,

I am a beginner, trying to develop TUSB9261 DEMO.

Currently, the USB bus interface of TUSB9261 DEMO is USB-B interface.

Is it feasible to change it into USB-A or USB-C interface for bus power supply and data transmission?

Looking forward to your reply.

Hi Chongyu,

You can make it work; however, USB-A type connectors are meant to be used for USB hosts, so it's not recommended.

A USB-C connector would be an option, but you would need to add a PD or CC controller in order to manage the USB Type-C orientation. Here is another E2E post for more information:
