Hi
I succesfully compiled Mbed mouse example and flashed my board. I hay wired usb cable to GND, PA11 and PA12.
User led blinks as expected but host computer doe as not recognize new device.
I’m doing something wrong. I watched video and I read documentation, but I’m new to the usb in microcontrollers.
Please help!

Hello,

STM32 targets what do not have onboard USB connector do not have USB enabled in default. It has to be enabled via mbed_app.json file.

{
    "target_overrides": {
        "*": {
            "target.device_has_add": ["USBDEVICE"]
        }
    }
}
