Bug Description
I have a usb Huawei e1550 mobile broadband modem from Starhub in SIngapore. This device worked fine under 9.10 but after upgrading to 10.04 the latest release fully patched this device is no longer detected as a mobile broadband modem. It is detected as a mass storage device as it also contains a micro sd card but the modem functionality isn't. Attached is dmesg output.
In 9.10 the device was detected and under networks a Mobile Broadband option was available. Under 10.04 no additional network device is available.
Hardware is a Dell Latitude d430

Try to use "lsusb" in terminal.
If you find string "12b1:1446" and followed by modem's brand, then this trick should work for you.
Open Gedit, copy this text :
-------
ACTION!="add", GOTO="huawei_
SUBSYSTEM=="usb", ATTR{bDeviceCla
SUBSYSTEM=="scsi", ENV{DEVTYPE}
GOTO="huawei_
LABEL="
ATTRS{idVendor}
LABEL="
-------
Do not copy the begin and end line, of course.
Save it on your desktop, named "15-huawei-
Press Alt+F2, type "gksudo nautilus", this will launch nautilus in Super-User mode.
Now open "/home/
Finally, open "/etc/udev/rules.d" and paste it there.
Restart your computer, and then plugin your modem.
Type "lsusb" again in terminal, if the string change to 12d1:1001 followed by your modem brand, you should be able to use your modem.
