Title:
  mbim-proxy uses 100% cpu with Sierra EM7345 LTE modem, unable to
  connect

Status in libmbim package in Ubuntu:
  Confirmed

Bug description:
  I have a Sierra EM7345 LTE modem in a Lenovo T450s.

  On boot mbim-proxy is using 100% cpu and the modem will not move to
  the connected state.

  I have to kill the mbim-proxy process to stop it using CPU, and I
  can't get the modem to connect at all.

  The problem also occurs with Ubuntu 17.04 run from a live USB stick.

  I've used this exact hardware with several previous installs of Ubuntu
  and never had this problem.
