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)
