Hello,
I'm not sure to understand your question.
SBSFU is not using USB.
Now on Nucleo boards, as well as discovery boards, the SBSFU uses the UART that is connected to the Embedded STLink MCU.
This STLink MCU is also connected to PC through USB, with usually 3 classes: STLink Debug, Mass storage and Virtual Com port.
The embedded STLink make the connection between USB VCP and a UART link going to the target MCU.
So, SBSFU only sees UART connection, but on PC side, as you are connected to the STLink, you can send and receive data through this VCP to the SBSFU.
I hope this is clear
Best regards
Jocelyn
