Hi. I'am developer from Russia. And, i have a problem. I generate project in CubeMX with Virtual Com Port (USB 2.0) and upload it in my device (STM32L-Discovery board with STM32L152RBT6). When i connect USB cable (Power from USB bus, cable from ST-Link disconnected), i have a message from Windows: ''device not recognized''. But, i have a test project from the internet, it's not working, but device is recognized. Whats wrong with project? HSE working from ST-Link resonator (I connect SB17 bridge)
This is my parameters:

Very simple, i got usb cable with connectors, and connect it to board.
I just generate project in CubeMX, and upload it on board. Device must be recognized, right? But, if i use project from the interned (Found it inhttp://myrobot.ru/forum/topic.php?forum=3&topic=501
), it recognized, but i can't send and recieve data, and i dont know why. I think about new library (HAL), and yesterday, itry it, but, it's not working. Maybe i'am a stupid?)

Hi raven.alex,
Did you select the Communication Device Class of USB Device in the pinout view? Give us your *.ioc.Try to program your board with the example under STM32Cube_FW_L1_V1.4.0\Projects\STM32L152D_EVAL\Applications\USB_Device\CDC_Standalone with taking into account specificity of your discovery board.-Shahrzad-
