What is the version of the SDK that you are using. I could not find it in my projects.
Hi Sai Krishna,
it is FX3 SDK version 1.1.1 release B818. I append you the .c file of the USBBulkSourceSink example.
This part of code is not compulsory to have in your projects.
It is just that we intended to show a piece of code to come back into U0 mode incase if you get stuck in any low power mode.
