I'm running Kubuntu 14.10 and trying to make an MTP connection (over a USB cable) to an LGP705 Android phone. At one time I had the connection working, but no longer. The problem I now have is that the device icon in "Available Devices" appears twice, but neither of these appearances is usable. One of them has the label LG-P705; the other has no label. How can I get back to having a single device in the list?
