This cable has completely stopped working after 4 months. I bought in April. By August, it doesn't charge anymore. I only used it to charge one phone. I have tried different wall adapters. The problem is with the cable. I wish I had never bought this cable.
Works as expected in my configuration: connect a "Targus" dockstation with my linux machine: except network (which was not expected to work, anyway), everything else goes through: disks, displays (via displaylink), sound, mouse and keyboard.
