L072CZTx not showing up as a Virtual Com Port

[David_ZG]

Hello all,

 

Im Currently working with my own Hardware with the L072CZTx on it.

I want to use a Terminal over the 2 USB Pins.(USB_DP and USB_DM)

I activated the Clocks with 48MHz

Activated USB

Activated USB_ Device as a Communication Device Class(Virtual Port COM)

 

I got told i should see it in the Device Manager as a Com Port or a unidentified Device.

Sadly i can only see my V3set im using to Programm the Controller with (SWD).

 

If very new to Programming with STM32 and if you have any ideas that could fix it i would really appreciate it.

 

Thank you in Advance

Do you have experience with any other microcontrollers ?

With USB in general ?

 

USB isn’t really a beginner’s project ...

I Used the Nucleo board with the L073 mC on it before to create a Prototyp of the Project i work on right now. Everything worked fine but it was with Uart.

 

For the USB Part i used a different Nucleo board with a USER_USB port on it but its completely Different then the mC that i use now it had THREADX and USBX.

I was kind of thrown into cold water with this Project
