I am trying to get my new Option card to work on Linux, but no such luck!
I have the "Option GT Ultra Express" card sold by AT&T, which supports GSM/GPRS/EDGE and UMTS/HSDPA/HSUPA, with download speeds up to 1.4 mbps, and which slides into the new ExpressCard slots.

And my Linux is the latest Ubuntu which is running the latest (as far as I know) kernel. "lsmod" tells me that I have the kernel modules "option", "usbserial", and "usbcore" already loaded.
When I insert the card, what Linux first sees is the ZeroCD volume and no /dev/ttyUSB's. I am able to run "usb_modeswitch-0.9.3" with this config

After this, I see two new devices,

And this is as far as I get. The tools comgt, umtsmon, and pppd all give me errors. What should I be trying next?
Oh, I should mention that on Win XP with the same machine and card, I am able to connect without issues. And that with the same machine, and the same Ubuntu setup, I was previously able to use a Novatel 3G card without problems.

Yay! "hso-1.1.tar.gz" and "hso-udev.tar.gz" worked nearly out of the box.
In case any AT&T customers find themselves in a similar situation, the only change you need to make is to this file "hso/connect.sh"
| Code: |

< export APN="internet.eplus.de"
< export USR="eplus"
< export PAS="gprs"
< export PIN="0000"
---
> export APN="isp.cingular"
> export USR=""
> export PAS=""
> export PIN=""

Thank you!!
One other question. I notice that "umtsmon" still doesn't work. Is there any way to get signal strength and/or other diagnostic info from the card?
