Comment 22 for bug 430011

First test with the latest kernel in the official repositories.

ii linux-image-2.6.31-14-gen 2.6.31-14.48 Linux kernel image for version 2.6.31 on x86/x86_64

The modem is "visible" as a modem during one minute or two but then the device or the USB controller seems to trigger a reset. The device is then recognize as a USB mass storage for a few seconds. Kernel logs bellow. I will test now with the patch.
