[Freeswitch-users] Help understand error message -- gsmopen fails

Latest FS (Git HEAD, as of yesterday), cloned and built successfully with
mod_gsmopen. Have used a fully unlocked E1550 dongle (tested in Mobile
Partner softeware in Windows, able to make calls, send SMSs). Started FS
with default configurations, as per Wiki instructions. Using the default
configration for gsmopen as well (maybe, that is the problem) ???

I get the highlighted errors, while loading mod_gsmopen ! My naive
interpretation (started with FS yesterday, and no experience with Asterisk
either), is that in the gsmopen module default config, I find:

  <per_interface_settings>
    <interface id="1" name="gsm01">
      <param name="controldevice_name" value="/dev/ttyUSB3"/>
      <param name="controldevice_audio_name" value="/dev/ttyUSB2"/>

However from the error logs printed in FS console, I see:

4a3d1a0|4a3d1a0[(nil)|37     ][NOTICA  3056 ][none      ][-1,-1,-1]
f.tty_data_device = |/dev/ttyUSB2|
2013-08-22 23:29:53.007103 [NOTICE] mod_gsmopen.cpp:3057 rev

f.tty_audio_device = |/dev/ttyUSB1|

Probably that is autodetected !! But how, without the IMSI/IMEI being
specified?

With this understanding, I went ahead and modified the gsmopen config file,
to:
  <per_interface_settings>
    <interface id="1" name="gsm01">
      <param name="controldevice_name" value="/dev/ttyUSB2"/>
      <param name="controldevice_audio_name" value="/dev/ttyUSB1"/>

then unloaded mod_gsmopen, and reloaded it, but now, I get this error:

2013-08-22 23:41:43.587104 [ERR] gsmopen_protocol.cpp:137 rev

on interface gsm01:

What does it need /dev/ttyUSB3 for ?

Maybe -- after all, my non linear progression into setting up FS and using
it by somewhat of trial-n-error isn't helping!

thanks,
Jay
