Bug Description
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 :(

For record (if [2] goes down).
Udev rule:
#TI USB 3410
SUBSYSTEM=
SYSFS{bNumConfi
SYSFS{bConfigur
RUN+="/bin/sh -c 'echo 2 > /sys%p/
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

I made some tests with that usb to serial converter and modem. =="0451" , ATTR{idProduct} =="3410" , RUN+="/bin/sh -c 'echo 2 > /sys%p/ bConfigurationV alue'"
First - I connected to my Gentoo laptop (udev-122, 2.6.25-gentoo-r1) and I got same error message in dmesg as in Ubuntu 8.04. I added new udev rule, replugged device and it started to work in Gentoo. Conclusion - issue is not only Ubuntu specific and it's fixable.
For reference - the new udev rule, that worked on my Gentoo box (2.6.15 kernel): SUBSYSTEM=="usb", ATTR{idVendor}
As next step I used same udev rule on Ubuntu 8.04 but without any luck - for some reason it doesn't work in Ubuntu.
More info from Ubuntu 8.04 box (lsmod, udevinfo and udevtest in attachment):
dmesg:
