I've got a Huawei E3276 4G modem from my telco and I can't get it to connect on Ubuntu Desktop 12.04.
Comment #11 at the following link is the only information I've been able to find regarding this modem and the telco Telia.
I ran the following command,
echo "12d1 1506" > /sys/bus/usb-serial/drivers/option1/new_id
but I get,
bash: /sys/bus/usb-serial/drivers/option1/new_id: Permission denied
I tried with
sudo without success.
I've tried eject the CD which gets mounted with the windows broadband software and that doesn't help.
I installed wvdialer, but when I run
sudo wvdialconf it fails to detect the modem.
I've also tried
sudo modprobe usbserial vendor=0x12d1 product 0x1506 but it doesn't make any difference.
