Seeking STM32 MCU with Dual USB 2.0 High-Speed (480Mbps)

Hi Sir,

Does any STM32 MCU support two independent USB 2.0 High-Speed (480 Mbps) interfaces simultaneously? I have observed that current H7 parts limit the second core to Full-Speed only. Do any newer series support true dual-HS operation?

Thank you.

    Nope. Just 1 HS + 1 FS max on a few different families.
