STM32 SDK 1.24.0 fails to reconnect HID-Usb on PC reboot

[CybDev]

I have got the following problem:

I am working with VisualGDB and updated my STM32 SDK from 1.23.0 to 1.24.0 and now, our device looses USB connection when the host PC restarts and doesn’t reconnect.

Th device sends a report every 5ms to the PC via USBD_CUSTOM_HID_SendReport. This seems to be the problem, as when i delete the line the device is reconnected.

I was able to reproduce this in an tutorial project using the following:

	RCC_ClkInitStruct.APB2CLKDivider = RCC_HCLK_DIV2;
	HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_5);

	To test it out:
		1. Install the ST VCP drivers (http://www.st.com/web/en/catalog/tools/PF257938)
		2. Connect to the virtual COM port using SmarTTY or any other terminal program
		3. Type some characters and observe the output

This outputs:

Setup:

Board: STM32F407VG

VisualGDB: 5.5 Preview 1

BSP: 2019.06 (= SDK 1.24.0)

ARM ToolChain: 9.21/8.3.0/r1

Packages:

– STM32F4 HAL Library

– STM32F4 Low-level Driver Library

– STM32 USB Device Library – Custom Human Interface Device

– Fast Semihosting and Embedded Profiler

This problem still exists using BSP 2020.01 (= SDK 1.24.2)

[TTimm]

the same thing with USB-MCS Device...

using SDK1.24.1

We have this reported directly to STM-Customer-Support:

Answer: ...and assigned to an ST support representative who will contact you shortly.

We will try to investigate this issue and we will inform R&D team responsible for STM32CubeF7 package about this issue

Thats all...

Kind regards Thomas
