Problem with USB Hish Speed on STM32F746G-Disco board

[ANDRE THEVENIN]

Hello,

I have problems with some STM32F746G-DISCO boards on the USB High speed port.

I have built an application which uses the USB-HS in host mode. On one board, it works fine, but on other ones I cannot make it work.

To test the hardware and not my software, I have built an application with STM32CubeMX with

-> a HID device on USB-FS

-> a VCP device on USB-HS

I have added the necessary initialization sequences for the HS port in the code generated by CubeMX (code below).

The result works fine on one board, I see both devices on the PC

But with other boardss, I see only the FS device.

The board which works is dated 1735 and marked JOVE JVE-M2 94V-0 E232940

One board which does not work is dated 1815 and marked SS-3 14V-0 E229342

Are there some design differences which could explain the problem ?
