how to make qmi call on android 4.4

IoT Modules MC/EM Series
1

Dear support:

       I used the MC7304 , and loaded the driver , now I can see the ttyUSB and  qcqmi ports  ,also there are two  wwan ports,wwan0 and wwan1

but when I run qmi call on the system, I failed.

I RUN the commad <adb logcat –b radio> , I Got the below log :

[b]we can see that  the mc7304 has been  detected ,  and the android system is also looking for usb0.   BUT there are only  WWANX ports on the system,  I don't know how to do next ,can you give me some advice ?  thanks.

Hi,
You can check the uevent.rc file, which is used to instantiate usb0 interface for the ril to communicate on it…

you can check the below lines:

SWISTART for Gobi Devices

/dev/ttyUSB* 0660 radio radio
/dev/qcqmi* 0660 radio radio

SWISTOP for Gobi Devices
