Hi, 

i'm working for usb project with ST32F072 with your example STM32Cube_FW_F0_V1.3.0 (CDC STANDALONE).

I'm trying to simulating a USB disconnect with USBD_DeInit ( &USBD_Device ), but apparently not work ( for PC the USB device is connected).

It's possible to know the way to reset all USB parts (software and hardware) , like a real cable disconnect ?

Sorry for my english !

    Your english is fine.

    On a previous project, with a processor from another manufacturer who I refuse to advertise for, we took Vbus and brought it into a DIO bit. When the device was unplugged, the DIO would change state and we would tear down the USB stack.

    I hope this helps.
