Title:
  Cannot connect to Android-Device using USB 3.0 and mtp protocol

Status in “libmtp” package in Ubuntu:
  New

Bug description:
  When setting my Samsung Galaxy S5 to "USB 3.0 MTP" mode, Dolphin
  cannot open any folders and shows the same device multiple times in
  kde hardware monitor.

  However, if I switch my SGS5 back to MTP (Standard, which means USB
  2.0 connection), it works just fine.

  
  The output of mtp-detect:
  $ mtp-detect 
  Unable to open ~/.mtpz-data for reading, MTPZ disabled.libmtp version: 1.1.6
