I was using GNU Make, I have switched to using MSBuild and the problem has gone away.

Thanks for the helpful suggestion.

Hi,
Thanks for the response.

I have a couple of Olimex boards, one with a STM32F405 and the other with a STM32F103.
Using STM32CubeMX, I can generate a Usb Cdc framework and import it into Visual Studio as per your tutorial.
Works great, both boards fire up ok and appear in Device manager as Com ports.

The STM32F302CB device is on a small header board. The board only has the 48 pin micro, a voltage reg, 8MHz crystal and the usb pullup components on the board. All the boards use the same Voltage reg, crystal and USB interface circuits.
I have scoped the osc and it is running at 8MHz. I have checked all connections with a meter. Power supply is good. I am reasonably confident in the hardware, I have two of the boards and they are acting the same.
I have the latest Firmware package for the device in STM32Cube.

I get ‘Device Descriptor Request Failed’ when I plug in the header boards.

Googling about, I have seen others having similar problems with the usb on the 302 device?

I will try to use a sample project that uses the same device to see if I can get it going.

I get the same problem using the Community version?
