Anyone? This is absolutely killing me. Sprint no longer sells the U720. I got the U727, and no dice so far. Ugh. 
Offline
yes this is driving me nuts too
Offline
I am waiting for my eee 4G surf as well as the Sprint U727.
I googled online for installing U727 on linux. Looks like it should be fairly easy.
Here are the links I found that might be helpful:
http://ubuntuforums.org/showthread.php?t=620209
http://www.evdoforums.com/thread7379.html
I think even it involves recompile the kernel, it should work in the end.
I'll report my experience later.
Offline
My EEE was delayed due to stock issue. I have managed to make U727 work under the default Linux environment.
I recompiled the kernel module usbserial.ko with CONFIG_USB_SERIAL_GENERIC=y.
and did following to load it into kernel
sudo modprobe –r usbserial
sudo modprobe usbserial vendor=0x1410 product=0x4100 ( U727 modem )
sudo eject /dev/sr0 ( the CD-ROM driver first being mounted when inserting U727 )
sudo dmesg|grep –i ttyUSB (not necessary but makes sure the driver loaded correctly, you should see ttyUSB0 for example)
The rest of it is the same as in http://samat.org/weblog/20070128-sprint … linux.html
My speed test shows a bit slow, like 491 kbs. Not sure if it is due to setup or due to firefox. But I am good to go.

hi there,
congrats on getting it to work. however, i am very new to linux and am unsure how to "recompile a kernel." is it simple enough to do? if not, i think i am better off getting a cradlepoint router.
Offline
It is quite easy. No need to replace the kernel image. Just need to rebuild a single kernel module named usbserial with an option. I think Asus should have done that with the default installation.
Here is the step-by-step for what I did to make u727 working:
0) open a terminal window. Either connect to internet via wire lan or copy files from anther computer using a USB sticker.
1) Follow wiki at http://wiki.eeeuser.com/howto:rebuildthekernel "Rebuilding the kernel on eeePC" part.
You can also try to download ASUS official release of linux on eee pc at
http://dlsvr03.asus.com/pub/ASUS/EeePC/ … 071127.rar
2) make usbserial kernel module with following cmd at the root where the linux kernel source code is located:
make CONFIG_USB_SERIAL_GENERIC=y M=drivers/usb/serial
3)
cd /lib/modules/2.6.21.4-eeepc/kernel/drivers/usb/serial
sudo mv usbserial.ko usbserial.ko.keep ( keep the old one)
sudo cp <to linux source>/drivers/usb/serial/usbserial.ko .
4)
sudo modprobe –r usbserial
sudo modprobe usbserial vendor=0x1410 product=0x4100 ( U727 modem )
sudo eject /dev/sr0 ( the CD-ROM driver first being mounted when inserting U727 )
sudo dmesg|grep –i ttyUSB (not necessary but makes sure the driver loaded correctly, you should see ttyUSB0 for example)
5) sudo ifup ppp0
assume ppp0 has been setup properly following the instructions at http://samat.org/weblog/20070128-sprint … linux.html
Then you are connected to internet.
Following link talks about using airprime instead of usbserial to get higher speed. I'll try it later.

Yep, switch to airprime and I get much better speed, same as if I test U727 on a windows machine one feet away.
Warning: Sprint official document uses usbserial not airprime!
Only need to add one line of code change into airprime.c
{ USB_DEVICE(0x1410, 0x4100) }, /* Novatel Wireless U727 */
and rebuild the kernel module 'airprime'
Offline
gosh, i am wondering if this applies to my sierra 595u. i am starting to think i cannot get it to work. maybe i need to get a u727.
Offline
@ ichelle, the Sierra card does not work. You all might want to check out this thread, if you haven't seen it already: http://forum.eeeuser.com/viewtopic.php?id=3326
Offline
yes, i was afraid of that! argh. guess i'm going to have to list it on craigslist or maybe find someone who is willing to trade it for a u727...thanks guys.

I've followed the steps above but I don't understand some things.
It was written:
I recompiled the kernel module usbserial.ko with CONFIG_USB_SERIAL_GENERIC=y.
and did following to load it into kernel
How do I enter the above into the kernel.
I'm not too good with the terminology. How do you recompile the kernel.

You can use airprime instead of usbserial. It gives you better speed.
If you choose airprime:
0) open a terminal
1) cd /usr/src/linux ( where you put the eee pc linux kernel source )
sudo cp /boot/config-2.6.21.4-eeepc .config
2) sudo nano drivers/usb/serial/airprime.c
insert
{ USB_DEVICE(0x1410, 0x4100) }, /* Novatel Wireless U727 */
below the other two lines with similar format , ie USB_DEVICE(0x???,0x????) }
(I do not have my eeepc with me so I can not check the exact line # )
3) sudo make M=drivers/usb/serial
this will make whole bunch of kernel modules, one of them is airprime. Ignore warnings if there is any.
4) cd /lib/modules/2.6.21.4-eeepc/kernel/drivers/usb/serial
5) sudo mv airprime.ko airprime.ko.old
sudo cp /usr/src/linux/drivers/usb/serial/airprime.ko .
This is to copy the newly compiled airprime module into right place for modprobe.
6) sudo eject /dev/sr0 ( to remove CD-ROM drive loaded when you insert U727 )
sudo modprobe -r airprime ( optional, just to remove airpime if it is loaded before )
sudo modprobe airprime
7) sudo ifup ppp0 ( assume you have that part done )
If you choose useserial,
skip step 2) above and in step 3) do
3) sudo make CONFIG_USB_SERIAL_GENERIAL=y M=drivers/usb/serial
Rest of it is explained in a post before.

Hi, can you please send me functional copy of the usbserial.ko module? A use your step-by-step manual exactly, but i getting this error message:

How to send it to you? I actually can also send you the airprime.ko that works for me.

Thanks zaurus 6k for the help. I could not get the U727 to work with the re-built usbserial driver -- still complains about the "vendor=" in dmesg, but I did have success getting it to work with the re-built airprime driver. Bravo!
One question: is it possible to rebuild the kernel module without going through the entire kernel rebuild, or is there something that the module rebuild "needs" from the kernel rebuild?
Also, I wrote a simple script to bring up the U727 evdo connection. It requires that wvdial be configured (I used the Sprint instructions). Here it is, for what its worth.
#!/bin/bash
#
# evdo.sh
# enables Sprint U727 EVDO adapter.

I just noticed something...after executing 'sudo eject /dev/sr0', a new device shows up in /dev, it is /dev/sdc. Looking back at the dmesg output it shows
[ 377.250000] sd 4:0:0:0: Attached scsi removable disk sdc
So it seems to me that the OS is automatically mounting the U727 as another sd card device instead of usb.
Any ideas?

U727 has a MMC_SD slot. That is what sdc for. Check your email. I sent you the .ko files.

I am posting this from my EEE via the Sprint U727.
Thanks zaurus6k!! Your files did the trick. I just copied your airprime.ko and usbserial.ko to /lib/modules/2.6.21.4-eeepc/kernel/drivers/usb/serial/ and now everything works great.
I wonder where i went wrong with mine...although i'm not going to spend much thought on it.

Does Asus plan on having "official" updates for the EEE?
I'm not an experienced Linux user -- I'd love for EVDO to just be plug-and-play --
is this a possibility?

Ok I have given up, been working on this for two days, and can still not get my system to compile airprime.c

Fix ASUS CD/DVD Omission
Install essential LINUX files left out by ASUS
All of the Download website points
