Hello,
I am working on a stm32u083rc. I'm trying to establish a USB Serial connection using the HAL_PCD library. I'm at the enumeration stage and trying to read the data sent by the PC (windows).
The USB device is initialized with CubeMX (STM32Cube FW_U0 V1.2.0) in Device only, Full Speed, interrupts enabled.
In my setup, I call the HAL_PCD_Start() function. Windows will detect a connection and attempt to enumerate it. At this point, the HAL_PCD_ResetCallback() function is called and I open EP0 in and out :

Hi @frangipane
Your device is still not addressed at this stage!
Do you have an issue using cube firmware example? Otherwise would you attach minimum project to reproduce the issue if present?
