Hi,
first off all, big and huge respect Josh that you run this forum alone! *thumb up*

I am using:
Samsung Galaxy Note 10.1 (android 4.0.4) + USB Connector
ppp Widget 1.15
ZTE USB Modem FFF1

If I connect my USB Modem with my Galaxy note, ppp Widget shows me "No driver found". I know that it recognize this USB Modem because the light of this Modem is blinking till this message appears "No driver found"

So, now I unchecked "Automatic device detection" and touched the widget icon. It shows me now
"1519:0020 (Comneon)".

So, if i now connect my Modem with my device and click then on the widget Icon, it shows me another option
"19d2:fff1 (ZTE, Incorporated)". After i chose this, it says again "not driver found"

Please help me. I am sure i need a configuration file, right? If not, is there any solution? I can remember on Ubuntu I had a configuration file and edit something. I cant remember any more, sorry. But i think it put a line equal to "0" and after that again equal to "1" and then it worked....

btw. I am not that newbie like the way i wrote :-)

The message "No driver found" means exactly that.

Any USB device needs a driver. The Linux kernel provides loads of them, but on Android kernels usually only few of them are available. It mainly depends on the device maker how he adapts the kernel for his device-specific OS version.

To make most wireless modems work, a USB driver is needed which supports serial (TTY) interfaces. There are two possible modules, "option" and "usbserial" (the latter as a fallback).

If these modules are not present on the device (and also not built into the kernel), there is nothing that PPP Widget can do.

You can try to find the modules in the file system of your device. Maybe they are in unusual folders?

Look for "option.ko" and "usbserial.ko".

[dahood]

Aww this doesnt sound good for me and I also wasnt able to find these 2 files on my tablet "option.ko" and "usbserial.ko". I guess to download it somewhere and copy it to my tablet wouldnt make much sense.
What would you now suggest to me? I live in Iraq and we dnt have many options to go online and it would be great if I could use my 3g dongle or 3g modem or option, I dnt know which one is the correct word.

[Josh]

You can copy those modules onto your device - provided they were compiled for your exact kernel version. Maybe someone has done that already ...

Newer versions of the "option" driver are split to two files so you would need the "usb_wwan" module in addition.

But before searching for modules (or even compile them on your own), check if they are not already built into the kernel. Look for the path "/sys/bus/usb-serial/drivers/option1"; if you can see this, the driver is active and the trouble with PPP Widget lies somewhere else.

[dahood]

Remember when i said "I am not that newbie like the way i wrote"? Well I think i was wrong, sorry!

So, i looked for this path "/sys/bus/usb-serial/drivers/option1" but after drivers, there is no "option1". Instead there is "pl2303" and if i click on this folder i get this this files: "bind", "new_id", "uevent" and "unbind"

I am not sure if its the fault of my Samsung Galaxy Note 10.1, because its a new device or is it the fault of Android 4.0.4. Maybe if I am gonna install another ROM, for example Cyanogonmod 10, would it work maybe? Maybe someone has done this with success...

However, all i can do now is to search in internet for the file "option.ko" and "usbserial.ko" and "usb_wwan". Lets assume they were compiled for my exact kernel version, where should I copy them?

Just for the records:
My Device's Kernel Version:
3.0.15-982379-user
dpi@DELL164#1
SMP PREEMPT Wed Aug 1 11:36:04 KST 2012

I did also a screenshot with more information about my Device, maybe someone else had the same problem.

[Josh]

PPP Widget will look for modules in these folders:

/system/lib/modules
/lib/modules
/sdcard/pppwidget/lib

To avoid messing with the system folders, I suggest putting custom modules in the sdcard folder.

[Josh]

I have provided the additional modules for a selection of Samsung devices.

See the new sticky thread on top of this forum.

[dahood]

Hi Josh
First of all, BIG thanks to you for not giving up this device "Samsung Galaxy Note 10.1"
Since Galaxy note 10.1 got so popular, maybe I am gonna be able to solve this problem now and other user can make benefit of this post.

I download the Attachment for my module "GT-N8000_modules.zip [221.98 KiB]" and it still doesn't work.
Meanwhile I updated my device to Jellybean, see picture.
I also added the "USB_ModeSwitch log" file.
I also copied and pasted my terminal, when I typed dmesg, into a text file and uploaded it because it is so long.

Can you see the problem? I hope it is not because of my dongle 3g modem

Just for the records, i dont have this folder "modules" in "/system/lib/" or "/lib/"
I have root access and I already looked for /system/lib/modules or /lib/modules. I just mention it because i noticed that you often ask the user to look inside these folder for files

[Josh]

At the moment, there is a problem with Samsung's JB kernels. The ICS kernels are accepting additional modules with few problems, the newer kernels don't.

You may need to be patient for a while ...

[dahood]

I have enough patience if that day comes, just infrom us, thank you in advance

[Josh]

Thank you for waiting ... we apologize for any inconvenience ...

I have found a way to check and match module versions properly. The new N8000 module package has a good chance of being actually useable. Get it at the "Driver Module" post.

[dahood]

Hey Josh,
Sorry for my late answer. I tried at the first day when i read your post, but it didnt work. But unfortunately i had final exams, so i decided to wait till Jelly Bean is out. now i tried it again with jelly bean. still not working.

But now i am there again and will daily check this page for the reason if you need confirmations with my GT-N8000. So please let me know what i can do, to help you. Its my honor to help.

[Josh]

Well, for the new kernel I would need one of the existing kernel modules from your device.

The most convenient one is "/lib/modules/scsi_wait_scan.ko". You can just attach it to your reply.

[Josh]

You can also look into /system/lib/modules.

It's important to catch a module (any module) which came with the device.

Here you are!
