hi @Chinmay.1 

Please have a look at this application, it is running on the STM32H743_EVAL board and using uSD & USB  drive simultaneously.

Hi @Haithem Rahmani ,

Thanks for solution. The solution that you are shared is using RTOS but In our project, we can't use RTOS.

Without RTOS, Can we mount & transfer files between two devices at a same time ?
