Public bug reported:

I have HUAWEI ETS1000 CDMA modem [1] and it was working just fine on
i386 7.10 after I followed instructions how to create custom udev rule
[2]. After Ubuntu upgrade to 8.04 those instructions doesn't help
anymore and no /dev/ttyUSB* device is created for modem.

Unfortunately this modem is far, far away and as it's only way to
internet from there, thus I can't post various ls*/dmesg stuff, but I
double checked, that idVendor and idProduct numbers reported by lsusb
match those listed in [2] and - more important - they where working in
previous Ubuntu release :(

2. http://blog.mohanjith.net/2007/06/installing-huawei-ets1000-on-linux.html

For record (if [2] goes down). 
Udev rule:
#TI USB 3410
SUBSYSTEM=="usb_device" ACTION=="add" 
SYSFS{idVendor}=="0451",SYSFS{idProduct}=="3410" \
SYSFS{bNumConfigurations}=="2" \
SYSFS{bConfigurationValue}=="1" \
RUN+="/bin/sh -c 'echo 2 > /sys%p/device/bConfigurationValue'"

dmesg messages after plugging in USB device:
ti_usb_3410_5052 1-1:1.0: TI USB 3410 1 port adapter converter detected
ti_usb_3410_5052: probe of 1-1:1.0 failed with error -5
