Comment 7 for bug 384344

After briefly failing to work with 0.7.1.git.3.7406e3a0e-0ubuntu1~nm1~intrepid1, Network Manager has started to work again with my card with 0.7.1.git.4.364ab2f86-0ubuntu1~nm1~intrepid1. I am enlisting the changes required on an intrepid machine to get a ZTE modem working so that the relevant changes can be made (how do I file this bug against hal-info?).

As a summary, these are the changes required for usbserial-supported ZTE 3G cards to function properly with network manager on intrepid:
1. [hal-info] Update /usr/share/hal/fdi/information/10freedesktop/10-modem.fdi to add 19d2:ffff:

5. Finally, I see a new file being installed by Network Manager: /etc/udev/rules.d/77-nm-zte-port-types.rules. It didn't seem to have any effect on the working of my modem (even after adding rules for product ID ffff). So, what exactly does this do? And, should I be making any updates here?
