Bug Description

SRU justification:

Impact: Missing ID causes hardware not to be supported.

Fix: Add ID (taken for Intrepid exeptionally)

Testcase: see below

Dell is distributing Conexant RD02-D400 USB modems with new notebook systems that have no internal modem.

These don't appear to be supported in Ubuntu 8.10, though the kernel module changes required to get it to work are trivial, see http://ubuntuforums.org/showthread.php?p=3684574

root@vostro:~# lsb_release -rd
Description: Ubuntu 8.10
Release: 8.10

root@vostro:~# lsusb | grep Conex
Bus 002 Device 003: ID 0572:1324 Conexant Systems (Rockwell), Inc.

The above link also shows that USB ID 0572:1328 should also be supported.

Ubuntu 8.10 with latest updates on plug in of this device gives dmesg entries as follows:

[10734.912211] cdc_acm: Zero length descriptor references
[10734.912214]
[10734.913761] cdc_acm: probe of 2-1:1.0 failed with error -22
[10734.914918] usbcore: registered new interface driver cdc_acm
[10734.916027] cdc_acm: v0.26:USB Abstract Control Model driver for USB modems and ISDN adapters

root@vostro:~# ls -al /dev/ttyACM*
ls: cannot access /dev/ttyACM*: No such file or directory

Seems that the 0x0572:0x1324 ID has hit mainline so we can trivially cherry-pick that back into Jaunty.

@dcam -- I have cherry-picked the upstream commit which adds the 0572:1324 ID to this driver back into Jaunty and built some test kernels. If you could test one of those kernels and report back here whether your modem is recognised that would be helpful. The kernels are at the URL below:

@dcam -- I note you are using Intrepid, so I have also built some Intrepid kernels based off the latest Intrepid -proposed kernel. If you could test those at least that would be helpful, though both these and the Jaunty kernels should work with your Intrepid userspace. If you can test both all the better. Either way if you could report back here that would be good. Intrepid kernels are at the URL below:

Andy, could you please include instructions as to what to do to get these deb packages of yours installed alongside other kernels (386 arch). Do I need to install the _all package and both other 386 arch files? Is it just a matter of dpkg -i or is it more complicated than that? I'm not familiar with this as I rely on the automatic update process.

@dcam -- you would want the generic header and the architecture specific header and binary for your preferred archictecture. For i386 that is:

    http://people.ubuntu.com/~apw/lp323829-intrepid/linux-headers-2.6.27-13_2.6.27-13.29lp323829apw1_all.deb
    http://people.ubuntu.com/~apw/lp323829-intrepid/linux-headers-2.6.27-13-generic_2.6.27-13.29lp323829apw1_i386.deb
    http://people.ubuntu.com/~apw/lp323829-intrepid/linux-image-2.6.27-13-generic_2.6.27-13.29lp323829apw1_i386.deb

You should be able to wget those three and then install them with dpkg:

    dpkg -i *.deb

This should add a new kernel to your boot loader screen.

Andy, with this new kernel of yours, it looks good.

and doing the following makes it go offhook and dial
echo ATDTnnnnnnnn /dev/ttyACM0

thanks!

that was meant to be:

The patch adds this one:

+ { USB_DEVICE(0x0572, 0x1324), /* Conexant USB MODEM RD02-D400 */
+ .driver_info = NO_UNION_NORMAL, /* has no union descriptor */
+ },

If anyone has a different modem they needs to file a new bug and include the lsusb output.
