When trying to connect using an HSO Option mobile broadband connection, the
applet indicates that it's connecting, followed immediately by a disconnect.
Looking at syslog, I see:
<info> Activation (ttyHS1) Stage 1 of 5 (Device Prepare) complete.
<info> (ttyHS1): powering up...
<info> Registered on Home network
<info> Associated with network: +COPS: 0,0,"T-Mobile",2
<info> Activation (ttyHS1) Stage 2 of 5 (Device Configure) scheduled...
<info> Activation (ttyHS1) Stage 2 of 5 (Device Configure) starting...
<info> (ttyHS1): device state change: 4 -> 5
<info> Activation (ttyHS1) Stage 2 of 5 (Device Configure) complete.
<WARN> hso_auth_done(): Authentication failed
If I manually configure the username, password and APN from the
mobile-broadband-prover-info package then it works normally.
