USB modem not working on Android 2.3

Keerthi Prakash

Hi sir,

I am Keerthi from Tenet Technetronics. I have problem in bringing up my USB modem on Beagleboard-xm using Android 2.3 OS. I have tried out the steps
mentioned in the below link

http://processors.wiki.ti.com/index.php/TI-Android-GingerBread-2.3.4-DevKit-2.1.1_PortingGuides#USB_3G_Modem

But still I have problem in accessing internet using my MTS blaze (ZTE) modem. I have pasted the logcat of "dmesg" and "/system/xbin/usb_modeswitch -I
-W -c /system/xbin/usb_modeswitch.conf" commands for your reference.

I think I have to set some rules in udev folder but I dont find a udev folder in my filesystem.

Please help me out in this context as I have to do project using this module.

Hoping a quick reply from your side.

Thanks,

Hi Keerthi,

Are you able to see the /dev/ttyUSB* entry getting created?

Hi ,

No, it is not created.Here is the my dmesg output.

Logcat of dmesg command

In normal Linux we write device rules (major/minor number) in udev, so same thing should we do it in Android?

Thanks,

Keerthi

Hi,

if your device is detected it will create a node under /dev like /dev/ttyUSB0 try to enable the drivers needed in kernel

cd kernel

make menuconfig

and enable the drivers in usb serial converter support for testing first enable all possible options and check if the node is created under /dev

Dibin
