This is related to an earlier blog I wrote about connecting my W41H up. I have recently bought a new W52T and found the setup is identical so I though I would elaborate on my earlier post within the context of a Gentoo install.
I'm using wvdial and the 2.6.19-r5 kernel.
Kernel Configuration
Device Drivers-->USB support
USB Modem (CDC ACM) support
Device Drivers-->Network device support-->
All PPP and SLIP/CSLIP Options
Grab wvdial
emerge -av wvdial
Add new udev rule (Optional Step)
Add the following line to /etc/udev/rules.d/40-kddi.rule
KERNEL=="ttyACM[0-9]", NAME="%k", GROUP="dialout", OPTIONS="last_rule"
Now reload the udev rules and restart udev:
udevcontrol reload_rules
udevstart
Configure wvdial
Step One: Plug the phone into the laptop using the cable that came with the phone.
Step Two: On the phone choose "Data Comm/Trans" within the dialog that pops up. If this does not happen you will need to search for the "Data Comm/Trans" option some where under USB setup on your phone.
Step Three: On your Linux box command line type the following: dmesg | grep acm
Look for something similar to this. In particular take note of ttyACMx:
[4294919.967000] cdc_acm 1-1:1.0: ttyACM0: USB ACM device
Step Five: Configure a ppp conection by creating /etc/wvdial.comf with the following contents:
[Dialer Defaults]Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2
Modem Type = USB
Modem ISDN = 0
Password = au
Username = au@au-win.ne.jp
Modem = /dev/ttyACM0Baud = 460800
Phone = *99**24#
Step Six: Start your wvdial connection by typing wvdial as root on the command line. To end the connection press ctrl+c. The amount of time the connection was up will be shown in the output of the wvdial command.
If you would like to see how many packets you have sent and received you can type ppstat -a whilst the connection is up.
And that's it :-)
