Title:
  Huawei E173 UMTS stick; sometimes not possible to activate mobile
  connection

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I have an Acer Aspire 1810TZ notebook running Ubuntu 13.10. When
  connecting my Huawei E173 UMTS stick, it is sometimes not possible to
  activate the mobile network connection in the network menu (when
  clicking on the network icon in the upper right corner).

  I attached the output of dmesg. The first time I connected the stick I
  cannot activate the connection. After disconnecting and reconnecting
  the device it works properly.

  Please let me know what you need additional information, this problem
  occurs in 1 of 3 tries, so I can reproduce it.
