We are trying to bring up 3G using USB Interface.
Setup:
Platform: OMAP 3730
Kernel: 2.6.32
OS: Android froyo (Rowboat release from TI)
3G hardware: Leoxsys
3G service provider: Airtel India
*No RF chip to support GSM Voice call on our device.
**We have tested the 3G hardware on PC and it is working fine.
**We are able to browse internet through LAN connection on our device.
Steps we followed to bring up the 3G on our board:
1. Enabled "ppp" and USB modem support in the kernel.
2. When we plug the 3G USB hardware on to our device, we get below
logs:

--> Assume the USB support is enabled properly in the kernel.
3. We are using chat binary with the script mentioned below(we are
using stripped down version of chat script):
-------------------- dialtest.chat -------------------
TIMEOUT 10
'' AT
OK ATE1
OK AT+CGDCONT=1,"IP","airtelgprs.com"
OK "ATD*99#"
CONNECT ''
4. We are running the "pppd" demon from the command line as below:
/system/bin/pppd /dev/ttyUSB0 115200 persist defaultroute usepeerdns -
detach crtscts noauth debug connect "/system/bin/chat -v -s -f /system/
etc/ppp/dialtest.chat"
Observation:
We are not able to connect to the internet using 3G USB.
Please help us out to resolve this issue.
