3G USB Modem support on Devkit8500

IndiSys Saxena
Prodigy 20 points

Hi,

I want to have 3G USB modem support on Devkit8500. I have followed the steps in the link

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

1. Completed the "Kernel Configuration for USB Modem "

2. Copy the usb_modeswitch (ARM Compiled binary) and usb_modeswitch.conf to the /system/xbin folder

Since I am using Tata Photon+ therefore I have modified  usb_modeswitch.conf file for the Huawei EC156 as

########################################################
# Huawei EC156

DefaultVendor= 0x12d1
DefaultProduct=0x1505

TargetVendor=  0x12d1
TargetProduct= 0x140b

########################################################

I have referred http://www.draisberghof.de/usb_modeswitch/device_reference.txt for usb_modeswitch.conf file

3) I will prepare a valid dialer script later. To prepare a dialer script following link will be used

http://www.dcaccess.net/welcome/linux/PPP-HOWTO-15.html

4) Disabled wireless and ethernet settings

5) On plugging the USB Modem following messages were printed on serial console

--------------------------------------------------------------------------------------------------------------------------

usb 1-1.2: new full speed USB device using ehci-omap and address 4
scsi0 : usb-storage 1-1.2:1.0
scsi 0:0:0:0: CD-ROM            HUAWEI   Mass Storage     2.31 PQ: 0 ANSI: 0

--------------------------------------------------------------------------------------------------------------------------

6) Executed the following commands

# su
# mount -t usbfs usbfs /proc/bus/usb
mount: No such file or directory

Since mount command has failed. Further I debugged and went to /proc/bus directory there is ONLY
input folder under /proc/bus

Also, No entry is found for "ls -l /dev/ttyUSB*"

Referring mail thread http://e2e.ti.com/support/embedded/android/f/509/t/169457.aspx, I have enabled all
the drivers in usb serial converter support.

Please support me get the Tata Photon plus (Huawei EC156) working on my DevKit8500.

Regards,
