STM32H7B3I EVAL Jumpering for USB Host

FrankNatoli

The STM provided USB host project has the following readme text:

- STM32H7B3I-EVAL Set-up

  - Plug the USB key into the STM32H7B3I-EVAL board through 'USB micro A-Male to A-Female' cable to the connector:

   - CN8 : to use USB High speed (HS), Make sure that JP9, JP11 and JP19 are fitted in USBHS position and that JP10 and JP16 are fitted.

   - CN27: to use USB High speed OTG IP in full speed (HS_IN_FS)

Attached is a photo of an unmodified EVAL board.

Are the five jumpers in position to support OTG FS?

Because, a USB mouse plugged into OTG FS shows no power, and the STM USB host driver does not detect the mouse.

Moving the mouse to OTG HS does not help.

The same mouse on an STM32H7B3I DK board does detect the mouse, but the USB host driver crashes, and I'm trying to use the EVAL with a Segger J-Link with memory write breakpointing.
