Init of cube MX USB CDC VCP stack

Hello,

 

I am using STs USB CDC VCP stack on a STM32L151.

Now I have the special case that some time I come to initialize it a second time, ie call MX_USB_DEVICE_Init(); though it is running. This does not take away the port from the windows device manager COM list but there are no more characters transmitted. I was looking through the sources but I can't find a reason (but I am not very familiar with it).

Please can anybody help with some idea.

 

Thanks a lot

 

Martin
