ZTE MF626 USB modem not recognized by network-manager 0.7

[RobertFullarton]

Binary package hint: network-manager

Network-manager(version 0.7) doesn't recognize this modem. (zte mf626 Telstra Pre-paid 3g)
I'm using Ubuntu 8.10.
I used usb_modeswitch to get the modem to switch to modem mode using the mf-628+ part of the conf file.

Currently this modem does work in ubuntu through the use of gnome-ppp.

I followed instructions at http://www.matt-barrett.com/?p=5 to get it going.

It would be great if this modem would work straight out of the box with ubuntu and network manager 0.7. This is a popular usb modem in Australia sold through the telco Telstra.

i was googeling because ia have a ZTE MF626 USB modem and i already tried usb_modeswitch and modprobe usbserial and everithing worked fine... but the modem disconnected after 2 or 3 minutes... sometimes longer connections... may be signal... but the thing is that i sonetimes unplugged the device and plugged back and "lsusb" showed nothing... i tried "dmesg" and showed

[ 3408.164107] usb 1-2: new high speed USB device using ehci_hcd and address 21
[ 3408.276063] usb 1-2: device descriptor read/64, error -71

[ 3409.036085] hub 1-0:1.0: unable to enumerate USB device on port 2

and looking for the error messages i found a russian website with some interesting things... try google translator and it understands quite well... it seems to be that the kernel has some "UNUSUAL_DEV"... and the numbers...

# cat /usr/src/linux/drivers/usb/storage/unusual_devs.h
...

...UNUSUAL_DEV( 0x19d2, 0x2000, 0x0000, 0x0000,
                "Onda ET502HS",
                "USB MMC Storage",
                US_SC_DEVICE, US_PR_DEVICE, NULL,
                US_FL_IGNORE_DEVICE),

i think this is the kernel source and they edited (commented that devices) and rebuilded and rebooted... and it works fine or kind of... or at least dmesg don't show nasty messagges...

As a comment, after unplugged my usb modem, and waited like half an hour, y plugged it back and "lsusb" show the damn modem.... so i can use modeswitch and modprobe to get connected again...

is there any chance to get an update (after a fix for this off course)... that connects me automatically?

http://www.gentoo.ru/node/12140?page=1

and recently it disconnects every 20 seconds after connet to my internet provider... annoying...
dmesg shows this

When I plug the key in ubuntu juanty latest beta I get:

Apr 1 13:36:44 m kernel: [ 9429.564296] usb 1-1: USB disconnect, address 9
Apr 1 13:36:52 m kernel: [ 9437.756068] usb 1-1: new high speed USB device using ehci_hcd and address 10

And of course nothing works.

The Jaunty bug is a huge mess, see https://bugs.launchpad.net/ubuntu/jaunty/+source/linux/+bug/305968/

I'm currently fighting with it now, I don't see a proper way to fix this. I really hope they sort something before Jaunty final.

My modem works after I used the howto from Ubuntu forums:

My ZTE MF 626 works out of the box in Karmic (beta). I just had to eject the ZTE-driver pseudo-cd after plugging it in for the first time.
