Telit TER-GX400 on Ubuntu/Gumstix

["Andy Maginnis" <jam smru co uk>]

Hi,

I am trying to get a Telit TER-GX400 HSDPA terminal working with network
manager on both ubuntu and a gumstix.
I previously was using a Three mobile ZTE MF112 and am using the same
sim card and settings.
http://www.roundsolutions.com/techdocs/docs_gsm_modules/TER-GX400.pdf

All seems almost well on Ubuntu, I get a download speed of 1/2Mbps and
an upload of 0.3Mbps, in line with the 
spec of this device, however the network is reported as "3 GSM" and not
"3 HSDPA", as I expected.

On the gumstix however my connection gets marked as invalid, with the
following message, when I try to connect to it? 

NetworkManager[995]: <info> Marking connection 'pbGsmConnection' invalid

Is this a simple setup issue or something more serious that I need to
fix? My settings are at the bottom of this email.

I was also wondering if I need to create a Telit plugin? The terminal
has several GPIO that I can control
with AT commands. But I can't access /dev/ttyUSB0 when network manager
has control(Note this is from experiments
on Ubuntu with NM disabled). What is best way to proceed?



Below is further info for debug, I've added some comments between #
symbols to try and make things clearer.
The settings are at the very bottom. Note this is a headless system.
