The information is enough or not?

try this

$ sudo modprobe -r option
$ sudo modprobe -r usbserial
$ sudo modprobe usbserial vendor=0×12d1 product=0×1404

and then “safely remove drive” on the mobile connect drive. works, but you have to do it every time, and the usbserial, option and vendor/prod id may change if other usb-peripherals are connected.

but, it's strange for me that ur modem string is
"Huawei Technologies Co., Ltd.", but not "Huawei Technologies Co., Ltd. EM660 USB Modem"

# sudo modprobe usbserial vendor=0×12d1 product=0×1404
sudo: unable to resolve host (none)
FATAL: Module usbserial not found

# sudo modprobe usbserial vendor=0×12d1 product=0×1404
sudo: unable to resolve host (none)
FATAL: Module usbserial not found.

# sudo modprobe -r option
sudo: unable to resolve host (none)
FATAL: Module option not found.
# sudo modprobe -r usbserial
sudo: unable to resolve host (none)
FATAL: Module usbserial not found.

could u provide output:

$ lsb_release -a && uname -a

just got it, please install this package:

$ sudo apt-get install usb-modeswitch

After $ sudo aptitude install usb-modeswitch, not solved

$lsb_release -a && uname -a

$ ls /dev/ttyUSB*

at the same time, I can use wvdial to connect Internet

$ sudo wvdial

so, u can connect by wvdial, i guess ?

ohh, usb-modeswitch will help on ubuntu 10.04 for NM

will u upgrade ?

I missed a comment, I can use wvdial in the Desktop PC, not the device

In the device
