I have the same problem. I have a Sony prs-650 which have worked fine until today. I use Calibre 0.7.18 and Ubuntu. Ubuntu can see both the internal drive of the device and the sd-card I have also. Calibre can't see the device anymore. I have not changed any settings. media.xml exists and a reset of the device didn't help.

Output from "debug device detection":
Version: 0.7.18
