Can't identify Nokia 3120 with DKU5

[John Hannfield]

Hello,
I have a nokia 3120 phone and a DKU5 USB cable.
All I need to do is to be able to send sms from the command line via this phone.
But so far I can't get gnokii to identify the phone.

I am using the gnokiirc config recommended by the wiki:

port = /dev/ttyUSB0
model = 6510
connection = dlr3p

Except on debian etch with udev I do not have a /dev/ttyS0

My USB DKU5 cable comes up as:

Bus 001 Device 008: ID 0451:3410 Texas Instruments, Inc. TUSB3410
Microcontroller

The Wiki says I need kernel driver "ti_usb_3410_5052"  for this device ID.
The module is loaded automatically in the kernel.

I created a udev entry to create a device for this:

BUS=="usb", SYSFS{idVendor}=="0451", SYSFS{idProduct}=="3410", NAME="usb_nokia"

Which udev creates as:

# ls -la /dev/usb_nokia
crw-rw-r-- 1 root root 189, 11 2007-03-03 17:46 /dev/usb_nokia

So my /etc/gnokiirc  is:

port = /dev/usb_nokia
model = 6510
connection = dlr3p
#connection = serial
#connection = dku5

But when I do a gnokii --identify it fails with:

# gnokii --identify
GNOKII Version 0.6.14
LOG: debug mask is 0x1

Gnokii serial_open: tcgetattr: Inappropriate ioctl for device

Has anyone got DKU5 cable working on debian with udev?
Any tips on using this phone with gnokii?

Many thanks,
