Hello everyone,

I am currently working on a project using the USB port to a PC host. My problem is that my device is detected as ''unknown usb device'' . Do you have any suggeestion?

Also I am looking for a USB firmware example code for my STM32L0 device, I can't find some anywhere.

Thanks in advance,

    Justine,

    You may start with examples in STM32Cube_FW_L0\Projects\STM32L053R8-Nucleo\Applications\USB_Device or STM32Cube_FW_L0\Projects\STM32L053C8-Discovery\Applications\USB_Device.

    Justine,

    If you are developing a Virtual Com application, install this VCP Driver for STM32.
