The "Introduction to secure firmware install (SFI) for STM32 MCUs" AN4992 does not list the H743 as a supported device.The Secure Programming tab of the latest Cube Programmer V2-18-0 (Jan 20205) states it only supports STM32U0-5 & WBA.Yet the SFI/S...

Yes it does, returning USBH_OK ***:- case USBH_HID_REQ_SET_PROTOCOL: /* set protocol */ classReqStatus = USBH_HID_SetProtocol(phost, 0U); if (classReqStatus == USBH_OK) { HID_Handle->ctl_state = USBH_HID_REQ_IDLE; ...

The set idle call seems to be important to maintain dataflow, is this change going to be needed to get the volume key data to arrive?case USBH_HID_REQ_SET_IDLE: // First Set_Idle for standard keyboard Report ID (0x00) classReqStatus = USBH_HI...

You are welcome to add support == Yet again STM has no support for even basic featuresIn my case even the ESC key was left out of the host keyboard map!A post on how to detect the volume up/down and mute keys would be useful as there is no documentat...
