In Hardy, I have to use the option driver:
modprobe option
echo -n '1199 0025' /sys/bus/usb-serial/drivers/option1/new_id
I use these udev rules to automate this:
SUBSYSTEM==usb, SYSFS{idVendor}==1199, SYSFS{idProduct}==0025,
RUN+=/sbin/modprobe option
SUBSYSTEM==drivers, DEVPATH==/bus/usb-serial/drivers/option1,
RUN+=/path/to/new_id 1199 0025 %p
SUBSYSTEM==tty, ATTRS{idVendor}==1199, ATTRS{idProduct}==0025,
SYMLINK+=modem
This is the script called new_id:
#!/bin/sh
if [ $# -lt 3 ]; then
echo 'too few arguments' 2
exit 1
fi
VENDOR=${1}
PRODUCT=${2}
DEVPATH=${3}
echo -n ${VENDOR} ${PRODUCT} /sys/${DEVPATH}/new_id
I believe that proper support from Sierra is forthcoming ... ?
Hope this helps.
Thanks,
Forest

I ran into the same difficulties on a project. The device is unreliable, I believe due to a driver compatibility issue (I think the device needs some special handling that cdc-acm does not provide). I did some debugging with it but lacked the time and expertise to finish the job. See this thread on linux-usb: http://kerneltrap.org/mailarchive/linux-usb/2010/2/19/6257991 Interesting that you are using the generic usb-serial driver. cdc-acm automatically bound to mine when I plugged it in. We ended up switching to the Sierra Wireless 598U 3G modem for our project. It works well with the option driver. Hope this helps.
