USB_MODSWITCH was to my rescue when I started using Ubuntu some time back and I am sure its going to rescue me on my android as well. Thanks for this very useful utility. This is why I liked linux in the first place

On my rooted phone, I have installed the PPP Widget. When I connect my USB Modem (Tata Photon Plus, HUAWEI EC156), ModeSwitch seems to happen fine.

Device ID on plugging in: 12d1:1505
After ModeSwitch I get : 12d1:140b

Its also indicated similarly in the logs. However, there is no driver found after that. I looked around to see if there are any drivers for this device/ kernal but did not find one. The details are below.

Phone Name: HTC VLE_U (HTC One S)
Android Version: 4.1.1
Kernal version: 3.4.10-g0f5103e (Stock HTC ROM)


The log from the widget is below. Please help

It would help if you could attach a stock rom module from your device to the post - just one. The smallest one is probably "scsi_wait_scan.ko" which usually sits in "/lib/modules" (only visible with root access, e.g. with "Root Explorer").

[varunksl]

Hi, please find the module attached.

[Josh]

Please understand that Wifi-only devices get a higher priority regarding creation of modules. You may need some patience.

[varunksl]

I understand. Thanks for your response see and the good work which made it easy / possible to use my photon device on Ubuntu. I am sure that once you have had time to look into it, my android will be able to use it too.

Thanks again

[varunksl]

Hi, I would need to travel next weekend and will need to rely on my photon for connectivity. Any chance of creating the driver before that? I can help create it and volunteer to create additional drivers if someone can explain how this is done.Thanks in Advance.

Try this modules

[varunksl]

I tried the attached modules. They dont work. I tried the following, as mentioned in the "Driver Not Found" thread. Please note, I did not have my usb key attached to my phone at this time. So, please let me know if I need to have that.

Installation

Just download the packages for your specific device and put the unpacked files to this folder (on your device):

[sdcard]/pppwidget/lib

Testing (troubleshooting and experimenting only)

Usually, you can see in PPP Widget's "USB Log" if the drivers that you installed in the "lib" folder were loaded correctly.

To test manually if the kernel accepts the modules, open a terminal app on your device, run "su" to become root, and navigate to the "lib" folder where your modules are.
Code:
$ su
# cd /sdcard/pppwidget/lib

From there, run the command:
Code:
# insmod <module_filename>

Start with "usb_wwan.ko". If there is no error, you are a lucky winner. Otherwise, run the "dmesg" command and note the last line of the output which should give you some more information about the problem.

I did get the below error.

u0_a227@android:/ $ su
root@android: # cd /sdcard/pppwidget/lib
root@android:/sdcard/pppwidget/lib #
insmod usb_wwan.ko
insmod: init_module 'usb_wwan.ko' failed (No such file or directory)
255|root@android:/sdcard/pppwidget/lib # ls
option.ko
usb_wwan.ko
usbserial.ko
root@android:/sdcard/pppwidget/lib #
insmod option.ko
insmod: init_module 'option.ko' failed (No such file or directory)
255|root@android:/sdcard/pppwidget/lib # dmesg

I than ran dmesg as suggested and the rather verbose output, Which I could not understand is attached.

[SileNTViP]

Try to load "insmod usbserial.ko" if successful load usb_wwan then option. and log dmesg

[varunksl]

Worked like a charm!!
One suggestion though.. we should mention that sequence in the "Driver not found" sticky thread. So, I am going to try it with actual device attached once I have it with me. I am sure it will work this time. Once it does, I will notify so that this driver can be added to drivers page for everybody else to use.

u0_a227@android:/ $ su
root@android:/ # cd sdcard
root@android:/sdcard # cd pppwidget
root@android:/sdcard/pppwidget # cd lib
root@android:/sdcard/pppwidget/lib # ls
option.ko
usb_wwan.ko
usbserial.ko
root@android:/sdcard/pppwidget/lib # insmod usbserial.ko
root@android:/sdcard/pppwidget/lib # insmod usb_wwan.ko
root@android:/sdcard/pppwidget/lib # insmod option.ko

[LOM]

Try this modules

Some huge drivers in there, did you forget to strip symbols?

[SileNTViP]

Try striped modules

[varunksl]

Yup, still works great and much smaller. Thanks

[Josh]

SileNTViP,

thank you very much for your help here!

I'm heavily time-constrained at the moment, so your work is extremely welcome!
