one-way audio with E1550

Test Environment:

debian wheezy kernel 3.1.0-1-486
E1550 firmware 11.609.18.00.00
asterisk version 1.8.9.0

The Audio is only in one way GSM->VOIP.

I used the instruction described here: 
"http://wiki.e1550.mobi/doku.php?id=troubleshooting#one_way_voice_on_huawei_e150
"

The audio works in both direction after loading the kernel module 
"huawei_voice.ko" as described in the link above BUT i get another problem. 
When restarting the dongle or unplug and plug it again then the kernel detect 
only one of the three ttyUSB port(only audio_tty) see syslog messages at the 
end.

I know this might not be chan_dongle bug but i hope there is someone who maybe 
had this issue and can help me solve it.

Another thing to mention is that E1550 was voice disabled  and I activating it 
following this howto: http://forum.gsmhosting.com/vbb/archive/t-1180897.html
