hi,

I have configured the same interface and it is working.

But I want to show the sd card as write protected. I don't want the files to be edited or deleted when connected to pc.

Can you please suggest a solution for this.

I'm having problems with the USB MSC which uses the SD card as an interface.
It takes about 10 seconds to be recognized, but normally it connects and is recognized, can you help me?
Here's my project:
The important part of my code is just in the path USB_DEVICE->App-> usbd_storage_if.c
