Question

STM32CubeProgrammer can see the USB device in DFU mode, but cannot connect.

 set the device to DFU mode through USB. It shows up in device manager. STM32CubeProgrammer shows the port USB1, and show serial number.  I can select the address 0x8000000 size 0x40 and click read and see the result. But when I click on the Connect, it just hangs and fail. On the FW side, which function it calls to connect? I need t debug why it cannot connect.
