Hi ,

I am trying to write 2 HIDs in one composite device in STM32F103R8 .But due to some unknown reasons my first hid is working fine but 2nd HID shows ''Code 10'' error in windows , '' not able to start the device '' error. What all changes should i do to transform simple Mouse HID code to Mouse + Keyboard composite hid code??? #stm32-hid-usb #stm32-hid-usb

''If the VID+PID is already known, Windows loads the known driver regardless whether it's a multi-function device or not. ''''Windows remembers the Class-Driver-To-VID+PID-binding for the next plug-in event persistently, probably for performance purposes. Therefore, when you swap your Interfaces keeping VID+PID, you earn errors. But you can get rid easily by uninstalling your device in Device Manager. This will remove the memorized bindings.''
