Just bought a Medion S15449 and USB devices are recognized but partially work. -I have an external USB audio card which is recognized by Windows but not by its own software -Kobo ebook reader is recognized as a device but Windows doesn't open it as a storage Both device are recognized perfectly with the same USB cable with another Windows laptop Same behaviour on all USB ports (2.0 and 3.0) Uninstalled USB controllers and reinstalled USB drivers but nothing changed Other USB devices work fine (keyboard, mouse, usb drives...)
