[Freeswitch-users] gsmopen help

Hi, 

I just tried on Raspberry Pi with a Huawei E1550 and I got 3devices - USB0,1,2, however, when making a call the USB device name seems changed to USB3,4. Seems whenever making a call the device changes even no mod_gsmopen loaded.

I tested I can send text message without problem. questions -

1) Is this because the audio is locked? How do I check if it's locked or not?

2) If not, why the device name keeps changing? it there a way to avoid that?

3) I got 3 devices when plug the USB, is that normal? how do I tell which one is control and which one is audio? It seems the last one is control. And the third one maybe 3G?

Thanks, below is some log from /var/log/message
