What version of the product are you using? On what operating system?

Asterisk 1.6.2.9-2+squeeze4, Copyright (C) 1999 - 2010 Digium, Inc. and others.

aloha*CLI> dongle show version
chan_dongle: Huawei 3G Dongle Channel Driver, Version 1.1, Revision 10

None of four modems connected to the box are discovered. 
When reconfigured to detect by IMEI - works good. 

Please let me know if anything else will be required to investigate and fix the 
issue.
