I have one of these USB to HDMI adapters; “Cablelera Adaptateur USB vers HDMI, USB 3.0/2.0 vers HDMI Audio Vidéo Vidéo HD 1080P Convertisseur pour PC, Ordinateur Portable HDTV Compatible avec Windows XP/10/8/7 (NO Mac & Vista), Small”
I was doing a firmware update and I accidentally unplugged it so now it is no longer working and is not recognized by my PC.
