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.
