low USB speed CDC stm32f407

Hi.

I need to create a device which is to transmit data to the PC at a rate of at least 1Mbit / s. For this I used Stm32f407vgDiscovery board, CubeMX to create a project, choose the USB FullSpeed, CDC class. Download and install VCPdriver. Applications to obtain data from the microcontroller I have written using QT. I was able to establish a connection between the PC and the STM32. The data is transmitted. But with a very low rate, approximately ~ 12kByte / s. Сan you advise how to raise the transmission speed?
Thanks.
