PPCGeeks - HOWTO: Treo 700wx as USB Modem (Feisty Fawn 7.04)

Follow this guide to use your 700wx as a USB Modem on Feisty
After much frustration I was finally able to use my 700wx as a USB Modem, I used pieces of three different howtos.HERE HERE and HERE(Sprint PDF)
(this part of the howto is provided by CRCarl (Ubuntu Forum)

I'll just give you what I did to get it going, after all, that's what a howto is for!

On your 700wx, start the Mode Link program and plug it into your USB cable attached to the comptuer, then

Code:

lsusb

look for your 700wx, mine listed as

Code:

Bus 003 Device 004: ID 045e:0079 Microsoft Corp.

Write down the vendor id which is the first set of numbers and then the product id which is the last set of numbers, Stop the Modem Link program and disconnect Treo from the USB cable.
Run

Code:

sudo gedit /etc/rc.local

Add these lines above "exit 0" use the vendor and product numbers your wrote down, make sure you start each number with 0x

Code:

/sbin/modprobe ipaq vendor=-0x045e product=0x0079

touch /var/lock/subsys/local

save and close

Code:

sudo /etc/rc.local start

To Test

Code:

tail -n 0 -f /var/log/message

Press enter
Start Modem Link on the Treo and reconnect it to the USB cable. If the driver loaded the output should look something like the following

Code:

usb 3-1: new full speed USB device using uhci_hcd and address 5

usb 3-1: configuration #1 chosen from 1 choice

ipaq 3-1:1.0: PocketPC PDA converter detected

usb 3-1: PocketPC PDA converter now attached to ttyUSB0

I had to use CTRL+C to get out of the output
If you didn't see the above output, Craig suggests a restart at this time
If you did see an output similar to the above, write down the information of where the PocketPC PDA converter is attached to.

**Make sure you're connected to the internet to download appropriate packages**
Download KPPP and KPPLogview
click on APPLICATIONS>ADD/REMOVE
Select ALL
Search for ppp
Select KPPP and KPPPLongview
Click APPLY
After it's done downloading and in stalling, close ADD/REMOVE
Now let's configure the KPPP to use the modem we configured previously
Click APPLICATIONS>INTERNET>KPPP
Click CONFIGURE>>NEW>MANUAL SETUP
Name the connection whatever you desire
Click ADD
enter #777 for the phone number, click OK>OK
this will take you back to KPPP Configuration
click the MODEM tab click NEW
name the modem whatever you desire
click the down arrow on the MODEM DEVICE and change it to the location that corresponds to the where your PocketPC PDA is attached to (mine is /dev/ttyUSB0) Click OK>OK, this will exit your out of KPPP CONFIGURATION
click CONNECT and watch your Treo connect you to the internet!

I rebooted my laptop several times, the only error I received once was that KPPP couldn't detect a carrier. I disconnected my Treo from the USB cable and waited a few seconds, then plugged it back in and this resolved the problem.

Good luck!!!
P.S. This might work with other distros too.
