    Interesting. I also have a Sony Xperia ZR running Android 4.1.2.
    My VID:PID are 0fce:5197 though, with ADB enabled.

    Strangely enough, running mtp-detect multiple times gave different results, one of them said

    Device 0 (VID=0fce and PID=5197) is UNKNOWN.
    

    and one of them gave me a huge list which unfortunately was larger than my terminal buffer so I couldn't save it, here is a small part (the last) of it:

    libmtp supported (playable) filetypes:
       Folder
       Text file
       HTML file
       RIFF WAVE file
       ISO MPEG-1 Audio Layer 3
       JPEG file
       BMP bitmap file
       GIF bitmap file
       JFIF file
       Portable Network Graphics
       TIFF bitmap file
       Ogg container format
       Advanced Audio Coding (AAC)/MPEG-2 Part 7/MPEG-4 Part 3
       MPEG-4 Part 14 Container Format (Audio+Video Emphasis)
       Abstract Album file
       Abstract Playlist file
       XML file
       Free Lossless Audio Codec (FLAC)
    

    Now, it seems to have stabilised at the following (also after I disabled ADB):

    libmtp version: 1.1.3
    
    Listing raw device(s)
       Found 1 device(s):
       0fce:5197 @ bus 2, dev 6
    Attempting to connect device(s)
    OK.
    

    Not quite sure what to make of this. Running mtp-filetree gives the same VID/PID as noted in the OP:

    Device 0 (VID=0fce and PID=0197) is UNKNOWN.
    Please report this VID/PID and the device model to the libmtp development team
    Attempting to connect device(s)
    LIBMTP PANIC: Could not open session! (Return code 8195)
      Try to reset the device.
    Unable to open raw device 0
    OK.
    

    Running mtp-connect also report VID=0fce and PID=0197.

    Not sure what it was, but one of the commands seem to have produced that list mentioned earlier as a file called "1", find attached. Hope that helps.
