Hi,
</div><div><br></div><div>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.</div>
<div><br></div><div>I tested I can send text message without problem. questions -</div><div><br></div><div>1) Is this because the audio is locked? How do I check if it's locked or not?</div><div><br></div><div>2) If not, why the device name keeps changing? it there a way to avoid that?</div>
<div><br></div><div>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?</div><div><br></div><div>
Thanks, below is some log from /var/log/message</div>
