Hello, I have questions about NVIDIA Jetson Xavier NX Design Guide USB Figure 6-1. and Figure 6-2.

[Q1] GPIO * is shown in Figure 6-1. Should I use GPIO00 when using USB0 Port as a recovery port?

[Q2] In Figure 6-2, GPIO00 is connected. When using GPIO00 on the recovery port, is it necessary to select another GPIO because GPIO00 cannot be used in host mode?

[Q3] In Figure 6-2, the OC of the Load Switch is looped back to GPIO00 to detect the OC. Is this function only available in GPIO00?

If GPIO0 is used for USB0 port, you can use other GPIO for OC of load switch of host mode port.
