I got this error when attaching my xperia ZR:

Device 0 (VID=0fce and PID=0197) is UNKNOWN

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

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.

Attached is the full output of mtp-detect.

Sony Xperia ZR (C5503)
