Hi Marcus, I have attached the output. To be safe, the output was taken while running under KDE (in which GVFS is not active, obviously). As you can see, the ID_SERIAL for both cameras is identical: Canon_Inc._Canon_Digital_Camera libgphoto2 version is 2.5.16. As an aside, I noticed only recently that at some point ID_MTP_DEVICE was removed as a udev property when plugging in MTP devices like phones. I assume its direct replacement is ID_MEDIA_PLAYER?
