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
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
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
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/
