Can the STM32H743 OTG_HS2 USB configured as Host FS mode transmit at 12 Mbps?

I have a custom board with an STM32H743ZIT6 on it. Configuring the OTG_HS2 controller with STM32CubeMx and STM32Cube_FW_H7_V1.9.0 as a USB Host and MSC, I can read a USB memory stick.

The question is: my oscilloscope shows the DM and DP lines being clocked at 6MHz. Is there a way to configure the OTG_HS2 to clock them at 12MHz?

6MHz square-wave signal consists of 0 and 1 which represent 12 MBit/s.
