Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we can't fix it because your description didn't include enough information. You may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem.
We have instructions on debugging some types of problems at http://wiki.ubuntu.com/DebuggingProcedures.
At a minimum, we need:
1. the specific steps or actions you took that caused you to encounter the problem,
2. the behavior you expected, and
3. the behavior you actually encountered (in as much detail as possible).
Thanks!

Using Karmic Koala 9.10 x86.

When i plug in my ZTE MF622, it is detected as a cd-rom or usb drive.
And it loads very slow, even booting lags if the modem is connected during boot.

On karmic
When lsusb'd on 9.10 it says
Bus 003 Device 002: ID 19d2:2000 ONDA Communication S.p.A.

lsusb on 8.10 and 9.10 it says
Bus 003 Device 004: ID 19d2:0001

But the modem works perfectly in the previous versions 8.10 and 9.04, and it is detected as Qualcomm.
Mobile Broadband (Qualcomm Incorporated ZTE CDMA Technologies MSM) in the network manager.
Suddenly it was broken on Karmic.

Sorry I know this is bug-report for Jaunty - however I have similar problem to corp.graph in Karmic AND this page showed up No #1 in Google, so I'd like to share the solution I found in this page for benefit of others.

The fix is quite simple :

I just renamed /lib/udev/rules.d/61-mobile-action.rules,
to /lib/udev/rules.d/51-mobile-action.rules

Then plugging in the modem works as it was in Jaunty (yes, my ZTE MF622 was working staright away, flawlessly, in Jaunty)

Don't ask me WHY it works though, I'm no expert on udev :-)
But if I may guess - renaming that file into a smaller number (from 61 to 51) make udev processes it in a more timely fashion.

Anyway, hope it helps others.
