ModemManager: HP ev2210 Sierra MC5725 not detected

Added bug link from
https://wiki.ubuntu.com/NetworkManager/Hardware/3G

I was the original adder to the table of this model, and never filed a bug until now.

I was able to get NM to detect the modem by doing:

$ sudo modprobe usbserial
$ sudo modprobe sierra
$ echo 03f0 211d > /sys/bus/usb-serial/drivers/sierra/new_id

I have not successfully connected with this yet.

This actually seems to be a kernel bug as the patch is for the kernel driver.

I recieved a Verizon Wireless Daypass today, and was able to successfully connect using the ev2210 Sierra MC5725 with Network Manager with the patched sierra module.

Updated (to apply to latest git) patch submitted to linux-usb list on vger.kernel.org.

The abovementioned patch has been included in kernel 2.6.34-rc6. From the changelog:

USB: Add id for HP ev2210 a.k.a Sierra MC5725 miniPCI-e Cell Modem.

There are further patches for sierra modems in kernel 2.6.34-rc7. From the changelog:

    net/usb: initiate sync sequence in sierra_net.c driver

    The following patch adds the initiation of the sync sequence to
    "sierra_net_bind()". If this step is omitted, the modem will never sync up
    with the host and it will not be possible to establish a data connection.

William Lightning - the patch mentioned in https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/511066/comments/11 is now part of stable updates as of 2.6.32.13, see review request at https://lists.ubuntu.com/archives/kernel-team/2010-May/010588.html. Please try this kernel as soon as its released to -proposed.

madbiologist - the patches you've mentioned are for 2.6.34 and as such no longer apply to Lucid 2.6.32.

Initial review shows that the device is detected by Network Manager. It appears to work with a deactivated account (I can connect and ping the DNS server that I am assigned).

I have reviewed and verified that the 2.6.32.14 in proposed fully works as required.

The patch will be part of the update to 2.6.32.13 (see Bug #583414).

Accepted linux into lucid-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

Tested 2.6.32-23-generic from lucid-proposed. It works as desired, using the cell modem currently to post this.

This bug was fixed in the package linux - 2.6.32-23.37

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-lucid' to 'verification-done-lucid'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Applied the requested tag.
