1. I'm using Maple mini of STM32F103CBT6 microcontroller.
2. I use trueSTUDIO.
I created USB Virtual COM with CUBEMX. (4.19.0)
It looks very simple and nothing wrong.
But it does not work.
I have confirmed that the board is normal.
If I replace the boot loader, it will work normally.
First, I set it as follows.
But Device Manager does not even search for new devices.
So I tried the same test on the Nucleo F446RE.board.
But the same problem occurred.
It does not appear in Device Manager.
However, I changed the settings below and succeeded in normal operation.
vbus_sensing_enable = DISABLE;
But I want to use it in STM32F103CBT6 and STM32F103RET6. (for test)
I attach a file generated from cubemx.
I need help.
Please let me know if there is someone who is working normally.
If it is affected by the ide tool, please tell me about the possible tools.
