USB Mass Storage bridge to monitor USB traffic

[SSune.1]

Hi

I have stm32f446re nucleo. Is it possible to make one USB traffic monitoring bridge using it?

(USB Storage or SDCard) <-----STM32-----> Computer

I am trying to do is to make one monitor to see what content is getting accessed from the computer from the mass storage or sd card etc.

Can someone guide on this?

Hi Again

I tried to make it work.

I have the SD card SDIO module. checked the connectivity.

Some time I can see the USB device is added, but when try to format it it does not work.

Attached the source generated with CubeMX.

What is wrong with this?
