gobi-loader does not start at boot via udev

[rhhoek]

Binary package hint: gobi-loader

After installing gobi-loader and installing the right firmware files on the right place, de gobi-loader is not started at bootup.
If you start the gobi-loader manually (sudo /lib/udev/gobi_loader -2000 /dev/ttyUSB0 /lib/firmware/gobi) there is no problem.

If the gobi-loader is not is not started at boot-up, you can also force loading by using the special switch on the lap-top to disable all wireless connections and after that enable these connections. In this case udev initiates the gobi-loader.

Udev also starts the gobi-loader when you go into suspend or hibernate mode and return into normal mode.

When you increase the udev-logging (/etc/udev/udev.conf) from 'err' to info or debug, udev starts the gobi-loader at boot-up.

udev will run gobi_loader for me when this file exists in /etc/udev/rules.d/ so I wonder if this is a udev issue.

Workaround:

sudo cp /lib/udev/rules.d/60-gobi.rules /etc/udev/rules.d/

Please have a look at the solution in this bug:
https://bugs.launchpad.net/ubuntu/+source/modemmanager/+bug/686418

The solution blocks modemmanager to access the QDL device (for firmware loading). If modemmanager accesses /dev/ttyUSB0 while gobi-loader still runs, it corrupts the firmware load and the modem stays uninitialized.

I can confirm the behaviour of udev explained in the bugs' discription. I'm using a Lenovo X201 with a Qualcomm Gobi 2000 UMTS Modem. In Addition I've discovered the following thing:
If I connect the AC Adaptor of my Laptop before booting, gobi-loader is executed by udev within the boot process.
If I boot without having the AC Adaptor connected udev doesn't execute the loader.

Here is my steps to make gobi 2000 works on my Lenovo x201 with Ubuntu 10.10 64-bit (kernel 2.6.35-25-generic)

1. Copy firmware files to /lib/firmaware/gobi
2. $ sudo apt-get install gobi-loader
3. Add following two lines to "/lib/udev/rules.d/77-mm-usb-device-blacklist.rules" (Jochen's post #3 for more details):

        # Qualcomm Gobi 2000 QDL
        ATTRS{idVendor}=="05c6", ATTRS{idProduct}=="9204", ENV{ID_MM_DEVICE_IGNORE}="1"

4. Change KERNEL to DEVNAME in line 3 of /lib/udev/rules.d/60-gobi.rules:

        ACTION=="add", SUBSYSTEM=="tty" DEVNAME=="ttyUSB*" GOTO="gobi_rules"
