Hello! I'm trying to find what is causing random device connect/disconnect sounds, but can't find the issue, I googled everything without luck. I tried to boot in safe mode, removing the usb controller from device manager... no effect. I recently reinstalled Windows 10 1909, but issue is still there. I got HWInfo64 report attached, and 2 screenshots of my troubled USB ports that, I think, causing random sounds to play. I have no idea what these ports are, since I only have mouse and keyboard connected to USB. HWInfo and USB Tree Viewer are showing some weird failures of unknown devices, also my BIOS is lacking of USB3_3 USB3_4 ports... Please help.
