Question about PB_10 configuration on STM32F405RG probably related to USB_OTG_HS

[mrguen]

Hello,

I am using a custom board implementing the STM32F405RG.
Arduino Core STM32: 1.9.0
Arduino IDE 1.8.13

I can't have the LED attached to PB_10 work with the blink sketch. Another pin like PA_14 works.

I can see that PinNamesVar.h assigns PB_10 as USB_OTG_HS_ULPI_D3.

#ifdef USBCON
  USB_OTG_FS_SOF = PA_8,
  USB_OTG_FS_VBUS = PA_9,
  USB_OTG_FS_ID = PA_10,
  USB_OTG_FS_DM = PA_11,
  USB_OTG_FS_DP = PA_12,
  USB_OTG_HS_ULPI_D0 = PA_3,
  USB_OTG_HS_SOF = PA_4,
  USB_OTG_HS_ULPI_CK = PA_5,
  USB_OTG_HS_ULPI_D1 = PB_0,
  USB_OTG_HS_ULPI_D2 = PB_1,
  USB_OTG_HS_ULPI_D7 = PB_5,
  USB_OTG_HS_ULPI_D3 = PB_10,
  USB_OTG_HS_ULPI_D4 = PB_11,
  USB_OTG_HS_ID = PB_12,
  USB_OTG_HS_ULPI_D5 = PB_12,
  USB_OTG_HS_ULPI_D6 = PB_13,
  USB_OTG_HS_VBUS = PB_13,
  USB_OTG_HS_DM = PB_14,
  USB_OTG_HS_DP = PB_15,
  USB_OTG_HS_ULPI_STP = PC_0,
  USB_OTG_HS_ULPI_DIR = PC_2,
  USB_OTG_HS_ULPI_NXT = PC_3,
#endif

Probably this pin is in internal pullup since it is constantly very dimly lit.

So, I suppose the USB_OTG_HS is configuring all these pins. How can I setup the board so it works as a usual USB device (like on the generic STM32F401 that is working prefectly on the same board)?

Issue #1196 shows some parameters to enable/disable HCP/PCD in , but can't find any reference about them (-DHAL_HCD_MODULE_ENABLED -DUSBHOST -DHAL_PCD_MODULE_ENABLED)
