I'm developing USB MSC features with chip STM32F779 using SD Card .

Now I can read/write/format data in SDcard.

But there is 1 issue is I can not do Safe Eject the USB from Window.

Window said that the device is “safe to remove�? but actually USB device still there and can read/write as usual.

So does USB stack support any event to detect USB safe eject ? And What is the proper way to do this ?

I see the issue is when I eject from USB icon on the right corner of the Window, it is ok.

But when I eject by right click USB Drive in Window Explorer it not ok .
