What is the default USB settings e.g baud rate, parity, stopbit, databit etc for STM32?

What is the default USB settings e.g baud rate, parity, stopbit, databit etc for STM32 when using USB_FS?

In this case I can only choose FULL SPEED 12 mb/s. Is that 115200 bps?

I'm using STM32F373VBTx processor

Then the speed you select has no effect. You can use whatever you want, it doesn't matter.

You are mixing up USB speed with UART speed. If you implement a serial port in USB, you can have whatever defaults you want.

So if I have USB, without UART. Then my baud rate etc are configured by the host e.g PC computer when I connect the STM32?

Yes, my USB at STM32 works fine, but I want to slow down the speed. Can I do that from the computer?

USB clock rate is fixed. If the PC and STM32 are connected purely through USB, you cannot change the speed.

If you are using a USB to UART adapter (such as ST-Link VCP), you can adjust the speed as needed in your terminal program.
