cannot mount smartphone anymore

[Emanuel Berg <moasenwood@zoho.eu>]

I use to use this little zsh

  #! /bin/zsh
  mount-smartphone () {
      jmtpfs $(mktemp -d phone.XXXXXX)
  }
  alias smph=mount-smartphone

to mount the Samsung Galaxy Note 2 LTE GT-N7105 16GB (t0lte,
Android 4.4.2) smartphone filesystem in my $HOME.

But suddenly it doesn't work, it says:

  Device 0 (VID=04e8 and PID=6860) is a Samsung Galaxy models (MTP).
  libusb_get_active_config_descriptor(1) failed: No data available
  no active configuration, trying to set configuration
  libusb_get_active_config_descriptor(2) failed: No data available
  LIBMTP PANIC: Unable to initialize device
  terminate called after throwing an instance of 'MtpErrorCantOpenDevice'
  what():  Can't open device

Idea?

TIA
