How to set the baudrate for USB Host CDC?

Hello,

I'm working on STM32F407VG board. During device enumeration, both the Host and Device use full steep 12MB/s.

After enumeration, can I set '115200 8N1' for the communication? I tried to call CDC_SetInitialValue() to set line coding, but it looks like it still uses full speed for communication from USB analyzer. The device is a USB-to-UART device.

Thanks!

The 

'115200 8N1' only applies to a physical UART - it does not affect anything in the USB part.

Right. Thanks Andrew.
