Hi,

'' I

am using STM32F103RBT6. I am trying to power up the USB CDC project generated by CubeMx. This however doesnt work- Computer doesnt see the device at all. I remember I used to generate such project for an F4 device and it worked just fine. I was wondering either there is any additional code that has to be run in order to turn this module on?

I am 100% sure that the physical connections are correct. USBDP is connected to PA12 and USBDM to PA11.

I would appreciate all help really, I thought this is going to work out of the box and I am short on time now. ''
