NM with CMOTECH CNU-680 / ice.net D-50

[Peter Åstrand <astrand lysator liu se>]

I'd like to use the CMOTECH CNU-680 
(http://www.cmotech.com/english/products/pro_05.html) (alias ice.net D-50) 
with NM. The modem starts up in CD mode and requires an ioctl to change to 
modem mode. I've created the cmotech-tools project 
(http://sourceforge.net/projects/cmotech-tools) which now includes a small 
program to do this switch. Connecting with wvdial works great.

To be usable with NM, I've also created a .fdi file:

<deviceinfo version="0.1">
<device>
<match key="@info.parent:usb.vendor_id" int="0x16d8">
<match key="@info.parent:usb.product_id" int="0x680a">
<match key="@info.parent:usb.interface.number" int="0">
<match key="serial.port" int="0">
<append key="info.capabilities" type="strlist">cdma</append>
<append key="info.capabilities" type="strlist">modem</append>
</match>  </match>  </match>  </match>  </device> </deviceinfo>

I don't know much about .fdi:s, basically I'm guessing here, but after 
adding this file as 
/usr/share/hal/fdi/information/20thirdparty/10-cmotech-modem.fdi, the 
device shows up in NM. I do wonder which package should include a file 
like this: Should I include it in my cmotech-utils package, or send a 
patch to the HAL project?

Selecting "Auto CDMA" in NM fails. I guess this is because no username or 
password is provided. For ice.net, both the username and password is 
public, "cdma" and "cdma", but of course NM doesn't know this? It does 
figure our the phone number (#777) automatically, though.

The problem is, manually creating a Mobile Broadband connection doesn't 
work either. See log below. Any ideas? I'm using Fedora9.

When using wvdial, the log is much shorter:
