Bug Description

Binary package hint: udev

Description: Ubuntu 10.10
Release: 10.10
Architecture: i386 netbook
Version: 162-2.1

In earlier releases of ubuntu the u530 card was detected in serial and got /dev/ttyUSB0 and /dev/ttyUSB1 from udev to work properly with modem-manager. Now the creation of the usb nodes are missing and the modem is not recognized by network manager.

The card is there but uddev create none usb devicenodes for it,

The same procedure on another laptop that was updated from 10.04 desktop to 10.10 desktop edition.
Architecture: i386
Version: 162-2.2

Something in 10.10 is missing or not included if a machine was installed from scratch with perfect ten. The merlin card asks for the pin and jumps inside gsm or umts on this machine. The nm cannot get online, but this is another problem that match not the basic problem above.

Now the modem is linked to /dev/MerlinUMTS when plugged in, this work with the serial_cs module. I only switched on the internal analog modem of the x41 thinkpad, then the merlin card works right too. I feel this is a bug, a pcmcia device should not depend on internal devices of a machine.

Conclusion for now: If the bios of the laptop has a serial port enabled, the described error does not occur, the card got it's own devicenode from udev. I dont know if we have a depend from pcmcia serial port to a real ttyS from the bios, if yes this bug can be closed.
