Hi Community, I have an annoying problem with my notebook Lenovo Yoga 460. It constantly showing a changed USB device. Windows 10 showing the popup, that it had found a new unrecognized device.
In the device manager the device is listed in the section "Universal Serial Bus Controller". The device disappear after a few seconds and it is found again after some seconds. This will never stop.
I updated all drivers , firmware, disabling the device, reinstall the device, update the device drivers and windows patches. I also run the Lenovo diagnostics without any findings. Nothing helped. I restore all BIOS settings. The problem seems to be solved by disabling the USB device in the IO Port Access section in the BIOS. In this case I can't use my USB ports.
Attached you will find a screenshot of the tool USB tree view of my system.
Any suggestions how to fix this problem?
Thanks in advance
