Since very recently I have problems connecting my Onyx Boox Darwin 6 via MTP on Ubuntu 18.04. ADB is working well, but trying to connect via mtp leads to a LIBMTP PANIC (see outputs below). I tried with both the latest original package on Ubuntu 18.04 (1.1.13) and the self-build 1.1.17. I tried also with different cables (which all work with my phone with MTP).

mtp-detect output:

libmtp version: 1.1.17

    Surprisingly for me it could connect again one day later without any updates or reboot of the computer (only sleeping mode). But the day I reported that error, I tried many times and it worked for all my devices, except this specific Onyx Boox (also rebooting this device several times didn't help).

    And today it does again not work for me, also after rebooting both the device and the computer (also trying different cables doesn't help).

    This error:
    error returned by libusb_claim_interface() = -6

    actually means the device is "BUSY" , e.g. blocked by another program, like gvfs or KDE.

    Check if your desktops filemanager shows it, and umount it from there if you need the commandline.

      Thanks for your reply Marcus. This time I have ignored what the KDE/Dolphin side of things is telling me when I plug in the phone. The usual "allow/deny" message from the phone, took "allow" obviously, then

      $ mtp-detect
      libmtp version: 1.1.16

      Listing raw device(s)
      Device 0 (VID=04e8 and PID=6860) is a Samsung Galaxy models (MTP).
      Found 1 device(s):
      Samsung: Galaxy models (MTP) (04e8:6860) @ bus 2, dev 2
      Attempting to connect device(s)
      Error 1: Get Storage information failed.
      USB low-level info:
      bcdUSB: 528
      bDeviceClass: 0
      bDeviceSubClass: 0
      bDeviceProtocol: 0
      {SNIP}

      and pages and pages of information. So you are correct, the BUSY was from KDE/Dolphin. Now I also uninstalled jmtpfs yesterday as I thought was was causing the problems, plus there seemed little or no support for it on Github.

      Can you advise how do I mount it now please ? I require it to be mounted as I use Beyond Compare to copy/compare filesets between the phone and computer. That requires a mount point.

    Checked in Synaptic and there was a go-mtpfs installed. Read up on that and

    $ go-mtpfs /media/peter/myphone
    2020/06/07 13:56:13 FUSE mounted
    2020/06/07 13:56:41 fetched "Grundfosliterature-6014959.pdf", 10439599 bytes in 336 ms. 31.0 MB/s
    2020/06/07 13:56:42 fetched "20200302_124804.jpeg", 198493 bytes in 11 ms. 16.7 MB/s
    2020/06/07 13:56:42 fetched "Screenshot_2019-11-26-16-18-42.png", 1821799 bytes in 54 ms. 33.4 MB/s

    It just sat there not finishing because I didn't have the & at the end.. I assume the files 'fetched' were in the Downloads folder of the phone, although I can see 7 there, not 3. This has resulted in the device being mounted.

    Is this all that is required, or should I reinstall jmtpfs and use that ?

    when launching go-mtpfs /media/peter/myphone
    can you check in another window if you can just open and access this directory?

    Similar would be with jmtpfs
    Both provide a filesystem view of the device that you then can use with other tools.

    when launching go-mtpfs /media/peter/myphone
    can you check in another window if you can just open and access this directory?

    Yes, I was able to do that yesterday. However this morning it failed on the mount

    go-mtpfs /media/peter/myphone &
    [1] 3293
    $ 2020/06/08 08:20:06 selectStorages failed: EOF
    ^C
    [1]+ Exit 1

    Couldn't access that path of course, so pressed Ctrl-C. Try again ..

    go-mtpfs /media/peter/myphone &
    [1] 3383
    $ 2020/06/08 08:23:30 FUSE mounted

    and now I can access that path. This is what I find in general terms, it is not consistent with the mounting.

    Similar would be with jmtpfs
    Both provide a filesystem view of the device that you then can use with other tools.

    Yes, however jmtpfs hasn't been maintained for a many years from the looks on Github and the changelog for it also reflects no activity. That's why I'm trying go-mtpfs now as it appears to be more frequenctly maintained. Is there another tool to mount the phone ?

    Possibly that error that came up about EOF was simply that explained at https://github.com/hanwen/go-mtpfs/issues/59#issuecomment-60502963
