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 MessageContent="55534243123456780000000000000011062000000100000000000000000000" ########################################################
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,
