Ciao Seven, sorry for answering so late. just seen your mail (I'm almost back from a long pause, I'll be completely back next monday). For checking if it's voice locked and unlocking it, check the wiki page about dc-unlocker, you'll need a windows machine and that program. About how the devices keep changing, I can think to low power problem, maybe? No clue at this moment in my mind. About how to be sure which device is data and which one control, is trial and error right now, but I want to automate it. Hope to do it next week, with a mod_gsmopen general revamp. Let me know how is going with raspberry and gsmopen -giovanni On Tue, Apr 16, 2013 at 3:28 PM, Seven Du <dujinfang@gmail.com> wrote:
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
