Hello,

could you please describe more in detail your application? What class are you using and what you want to achieve?

You could find more information also in STM32 USB training session: https://www.st.com/content/st_com/en/support/learning/stm32-education/stm32-moocs/STM32-USB-training.html

Best regards,

Please take a look into STM32 USB training material, there is also chapter with USB MSC host example https://www.youtube.com/watch?v=dC0d8CVEPrQ

And you can find examples in STM32 repository installed with STM32CubeMX packages on your PC. Please look for STM32Cube\Repository folder and MSC_Standalone demo project.

What about the filesystem on USB stick? Is it formatted to FAT? Have you tried more USB sticks?
