I have generate a STM32H743ZI with CubeMX as HID-Host on PB14,PB15.

I get no Interrupt to set is_Connect flag.

When is an Interrupt generate in OTG_GINTSTS->HPRTINT?

I try it again with CubeMX to create a simple HID Host with OTG2 (PA11,PA12) and connect a mouse over an OTG cable. No Interrupt, no connection. With the debugger under True Studio I see that the IRQ is enable. PowerSwitch (STMPS2151STR) works and is ON.

Hi @Grisby​ ,

Please make sure to enable the USB voltage level detector after starting the device process. 

 MX_USB_DEVICE_Init(); 
 /* USER CODE BEGIN 2 */
 /* Enable the USB voltage level detector */
 HAL_PWREx_EnableUSBVoltageDetector();
 /* USER CODE END 2 */

Khouloud.

The voltage level detector is not optional?

I'm having similar problem with the NUCLEO-H743ZI.
