I can confirm the problem on Xubuntu 17.10. I think the problem is caused by braces "()" in file names. [1] The MTP backend does not seem to like them.
It can be reproduced as follows: 1. Check that mtp works in general 2. create a regular file with only "a-z0-9" chars in a dir on your MTP device 3. mount and access it from Linux. This should work in most cases. 4. Now try the error case 5. create file with braces "()" in a dir on your MTP device. 6. mount and access it from Linux using `thunar`, `nautilus`, or even using `ls` or `cd` on the command line. This should produce the file manager (or console) to hang and no longer respond to user input, etc. I also suspect this bug to be the cause for other bugs, e.g. in `gvfs` [2] [1] related error report at askubuntu https://askubuntu.com/questions/995383/nautilus-hangs-on-accessing-dcim-camera-on-android/1013351 [2] maybe related gvfs bug https://bugs.launchpad.net/ubuntu/+source/gvfs/+bug/1314556 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libmtp in Ubuntu. https://bugs.launchpad.net/bugs/1263355 Title: Unable to directly access files of any smartphone from Ubuntu Status in libmtp package in Ubuntu: Confirmed Bug description: Unable to access files of Samsung Trend from Nautilus, when you connect device a problem happens: "Unable to mound Android, Unable to open MTP device '[usb:003,003]' " If i try to access files such music or pictures in Android device, i get some errors.
