Kyocera KPC650 w/ Verizon Broadband (working!)

[ksaling]

I have this working (partially) on Ubuntu Hoary 5.04. Here is what I did.

1. Got the card activated by a buddy who uses the same card in his Apple Powerbook. Apparently, the KPC650 is now supported on OSX and even comes with the Verizon AccessManager software. So, he ejected his card and inserted mine, "Activated" it and updated the Preferred Roaming List (PRL). Note: this step can also be done on a Windows box I suppose.

2. Insert card in Ubuntu laptop

3. rmmod usbserial ; modprobe usbserial vendor=0xc88 product=0x17da

4. mknod /dev/ttyUSB0 c 188 0 ; mknod /dev/ttyUSB1 c 188 1

5. Created an /etc/wvdial.conf file like this:
[Dialer verizon]
Phone = #777
Password = vzw
Username = {my.verizon.phone#}@vzw3g.com
[Dialer Defaults]
Modem = /dev/ttyUSB0
Baud = 115200
Init = ATZ
Dial Command = ATDT
Stupid mode = 1


Now, I just do `wvdial verizon` to bring up the ppp0 interface and connect. This works well for several minutes (haven't tested b/w yet, but it seems very fast).


THE PROBLEM
After a few minutes, the ppp0 interface stops sending traffic. I can kill the wvdial session, which drops the ppp0 interface, but I cannot redial. At this point, the card seems to be in an unknown state. wvdial just prints garbage on the console when I try to dial. If I eject the card and reinsert, I can repeat this cycle.


SOLUTION?
I think this will fix it:
http://www.junxion.com/opensource/linux_highspeed_usbserial.html

However, I cannot get this to compile on Hoary 5.04 using 2.6.10-5-686 or 2.6.10-5-386. I get this:

Hrm. Replying to myslef. Not a good sign.

Well, turns out 2.6.10-5-686 was the problem. I got this to compile in 2.6.10-5-386 and it works great. Bandwith is consistently at or above 400Kbps and it runs for hours with no disconnects.

Unfortunately, the -386 kernel only sees the first 900MB of my 1GB of RAM. :( That was the whole reason I switched to -686 in the first place. Looks like I have to choose between 1GB RAM or Verizon Wireless.

I'm going to be getting a verizon card soon for work. I'm not sure if I will be getting the Kyocera, but do you think your instructions should work for any model, or is this specific to the one you have? I also have breezy on my laptop, could this affect its performance as well? Thanks in advance.

[gaucho]

WOW! Thanks for this! I am working on setting mine up, but being a complete noob to Linux I need some help.

I have never compiled code in Linux and would love to have a sort of step-by-step guide (i.e. what compiler do I use, where do i specify the kernel I'm currently on, etc...)

your help would be greatly appreciated it!

Thanks!

Nevermind, I found a step by step but now I am having difficulty making sense of the instructions on the reffered link... studying up on my C...

Instead of using that gcc command, I switched in the kernel source top level directory (/usr/source/linux-whatever) and issued a "make modules". This worked, and recompiled the module. I then copied it over the existing one and was able to load it issueing the maxSize paramter. However, still slow with Verizon's network and disconnecting every two minutes or so.

What maxSize did you use?

[Jim March]

In case anybody else is wrestling with this, see my post here:

http://ubuntuforums.org/showthread.php?t=157113

It's a weird but good solution involving hardware and zero drivers.

[Praxicoide]

I'm wrestling with this, but the solution you offer (which is a very good solution, in a way) is being sold here for US$400.00, which is lot more than what I can afford at the moment.

The guy with the service provider recommended that to me also.

Anyways, I'm trying to follow the maxSize patch, and in my /usr/src folder I have two folders: linux-headers-2.6.17-10 and inux-headers-2.6.17-10-generic

My understanding is that I have to cd to one of them and then put

diff -Naur drivers/usb/serial/usbserial.c drivers/usb/serial/usbserial_junxion.

is this right? and from which one do I need to do it?

[Megaqwerty]

I have been frusterated with this issue as well. I'm glad someone figured out how to get it to work!

However, I can't proceed as I don't seem to have the usbserial.c file.

Is the an apt-get command or something to download it?

Thanks,

Okay, I have one (hopefully) final problem. When I use your command for compiling the source code (it seemed to work for you in the end) gcc has errors.

I really want this to work. Can someone post their patched usb-serial.c file? It would appear I didn't apply the patch correctly.

Thanks,

Megaqwerty

EDIT: nevermind, I got it working using make modules.

[rushkoff]

Can you post your step-by-step? I'm assuming it's for 6.10?

There's a bunch of people over on the EVDO forums who I want to share this with, as well.

Well, I'm not the original poster, but here is how I got it to work:

First, you need to download the linux source code: sudo aptitude install linux-source Then do this: cd /usr/src
sudo tar xvjf linux-source-*.tar.bz2
cd linux-source-*/drivers/usb/serial
sudo nano patchfile

+MODULE_PARM_DESC(maxSize,"User specified USB endpoint size");

Save, and exit. Then we have to apply the patch: sudo patch -p0 < patchfile

We now have to go back to the top level and issue "make modules" cd ../../../
sudo make oldconfig
sudo make modules

Then, after that's finished, we need to make a backup of the old usbserial.ko, and replace it with our patched one. sudo cp /lib/modules/`uname -r`/kernel/drivers/usb/serial/usbserial.ko /lib/modules/`uname -r`/kernel/drivers/usb/serial/usbserial.ko.backup
sudo cp drivers/usb/serial/usbserial.ko /lib/modules/`uname -r`/kernel/drivers/usb/serial/usbserial.ko

Now you can consider your driver patched.

You can change whatever you had to modprobe usbserial to add the newly added maxSize parameter so it looks like this: sudo modprobe usbserial vendor=0x0c88 product=0x17da maxSize=2048

The methods in all the other posts to dial never worked for me, and I was too lazy to make them work, so I created some that do. If you want me to post them, just ask.

If you have further questions, I'll try to answer them as soon as I can.

Good luck,

Thanks! I'm just starting over with 7.04, and will try this on there.

Hi, I wanted to tell you that you will probably run into an error while following my steps to patch usb-serial.c due to the many updates to the kernel since my last post.

I am editing my tutorial to work with any kernel in the future (assuming the way linux handles things doesn't change too much in the future.) However, the one part of the tutorial that I can't guarantee will work with new kernels is the patchfile, so please post here if you need me to update it, and if for some reason the forums don't alert me to the new post, you can try PM'ing me as well.

Anyway, here is the updated patchfile for the 2.6.20 kernel:

Hello. I also have a Kyocera KPC650 eVDO card, and would like to get it running under Ubuntu Feisty. I tried following the instructions on the first post of this thread, but after trying rmmod, I get the message "Module usbserial is in use by airprime", and that's as far as I get. Being new to these type of proceedings, I really don't know what to do. I guess I have to stop "airprime", but I don't know how to do it, or what it is.

Any help would be greatly appreciated.

[Megaqwerty]

sudo rmmod airprime

Hope that helps,

I tried the directions in the first post, and after typing the rmod command I get:

The First message means that you have already removed usbserial from the kernel, and the second line is saying you need root privileges to do whatever you were doing there (this can be remedied by putting sudo in front of the command.

Now, when I enter:

but I have no internet access. It is even showing what looks like valid ip addresses. I feel like I'm close. What should I try now?

[Megaqwerty]

You are very close indeed! You need to run: sudo route add default gw 66.174.26.4 Where 66.174.26.4 is your remote ip address.
You should now have internet access.
