Hello,


Can you please share the UART debug logs of the issue that you are facing or share the snapshot of the error that you are mentioning?


Also, i tried the firmware that you have attached and i noticed that you have commented out the DisableUSB20connection() function in the ReConnectUSBphy() function.

Please uncomment it and then try using checking the USB mode change from USB 3.0 to USB 2.0 and then again to USB 3.0.

After uncommenting the function i am able to see the USB transitions of the USB PHY as expected.

Regards,
Yashwant
