huawei usb-modem (12d1:1003) not detected

[Andreas Moog]

Binary package hint: network-manager

1. I had to pass usbserial.vendor and usbserial.device - options via grub to kernel for the modem to be recognized.
2. Excerpt from syslog:

Result of udevadm info --query=all --path=/sys/class/tty/ttyUSB1 --attribute-walk attached.

I have the Huawei E220 and it cause the same problem.
If udev can't detect the serial Interfaces, it can't connect ppp via NetworkManager and pppconfig (& pon).
In such timings, I have to send any ATcommand to /dev/ttyUSB1 first, and then it can understand ATcommand via /dev/ttyUSB0.

So, I think udev have to send any ATcommand to this modem's /dev/ttyUSB1 first, then detect the /dev/ttyUSB0.

I can confirm this bug. Since I urgently need a working UMTS stick, I'd be very glad if someone could please tell me what I can do now to work around this problem. (Dist-Upgrading hardy is not an option at the moment and the older packages apparently left ppa already so I cant go back).

Update: Using the rules file from

https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/346835/comments/11

solved the problem for me. Thanks!

[sunatomo (naiyu)]

Above udev rules solved this problem too.
But my modem uses HSDPA network and it have to detect the wireress connection using "AT+CGREG?" not for "AT+CREG?" (if you use GSM network ,it can detect wireless connection using "AT+CREG?").

Andreas:
does this bug still appear in Ubuntu 9.10 or 10.04?

[iav (iav)]

Modem detects and work if usb-modeswict package was installed; if not - bug still active for daily-desktop 10.04

[Przemek K. (azrael)]

This should be fixed now as usb-modeswitch is included in Ubuntu 10.10
