IMEI discovery for Huawei E173 modem does not work.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Configure chan_dongle to do modem discovery through imei. i.e. audio, data, 
and imsi commented out and imei set to that of the dongle in dongle.conf
2. Run asterisk with debug mode on.

What is the expected output? What do you see instead?
I expected chan_dongle to detect the device based on imei but it kept on giving 
the following lines of code.

What version of the product are you using? On what operating system?
Version 1.1 R26. (svn download on 5 May 2011)

Please provide any additional information below.
I looked in to the pdiscovery.c file and noticed a struct static const struct 
pdiscovery_device device_ids. This struct does not have the vendor id product 
id for E173 listed. For E173 it is 12d1:1436. I tried adding an entry but that 
dint work probably because I got the port numbers wrong. If you can tell me 
what those numbers mean I can try at my end and contribute a patch for doing 
discovery for E173.

Sorry I forgot to add that I am running asterisk on Ubuntu 10.04. Kernel 
version 2.6.32-24.

Lot of peoples works with E173 and using discovery by imei fine.

So, i think you not prepare dongle for working with chan_dongle, you dongle 
has wrong device id.

Please read http://wiki.e1550.mobi/ carefully.

Issue will be 'Invalid' soon.

Thanks for the pointer. I have not run any of those preparation tools. That is 
because my device works (voice calls and SMS) without doing any of them. So 
with voice activated, and device already unlocked, do you suggest I do firmware 
update so that the vid/pid values are right?

use mode_switch for corrent device ids and interface -> port maps
