Description:
I am working with the USB mass storage example provided in github.com/.../mass
The example works as expected when built and flashed using NCS v2.6. However, when I attempt to build and run the same example using NCS v2.8 or v2.9, the functionality no longer works.

Flash the firmware to the nRF device (nRF5340 DK)
Are there any known changes or breaking updates in NCS 2.8/2.9 that could affect the USB mass storage functionality?
Thank you for your assistance!
