huawei e220 hardy alpha 5 - problem

[Guimenez]

Hello.

After install Ubuntu Alpha 5, when i connect my huawei e220, it detects the modem for about 1 minute and then it looses the modem.
Its doing a loop without stopping (detect modem then loose modem).
I've type "lsusb " and i see that sometimes it detects the storage and the modem, and after while, it detects just the storage.

With gutsy it install fine without no problems

Please help-me i want Hardy...

PS: After installation it gives me always the language error PT_pt, but i fixed choosing the language at login screen, but hope you fix that
in the final release

Thanks

Guimenez

Any Information in /var/log/messages?

[Guimenez (guimenez)]

thanks for replying.

i've attached my "/var/log/messages" for you to see the problem.

I've installed hardy for about 6 times, and its always the same.
when i make lsusb, it detects the "chicony Electronics CO" and "Huawei Technology CO e220 hsdpa modem" and after 1 minute it just detect "chicony Electronics CO" and modem nothing :(

Thanks

Same here with latest updated Hardy. It worked perfect in gutsy, but with Hardy it is detected but is then "disconnected" a few seconds later. It does this in a loop until it is unplugged. See the dmesg output below containing lines from when the device is plugged in to when it is lost.. It is usual that it is detected as 2 serial ports and a mass storage device (the storage device just contains the windows drivers) though I'm not sure about it being detected as a CDROM though.

Strangely, network-manager is seeing the hal device notifys. Not sure if that is normal (copied in below too)

Ok i found the solution.

Install the huawei.tar.bz2 (http://oozie.fm.interia.pl/src/huawei.tar.bz2) and then plugit again and it works like a charm

Instructions:
- Download the file
- Extract the file
- Go inside the folder you0ve extracted
- sudo ./make install_ubuntu
- connect again the modem

I hope final release of hardy they put this patch

It's done

I cherry picked from oozie just what is needed to stop the usb disconnect (basically, i think udev needs to load usbserial with those vendor and product strings whenever it spots the huawei cdrom device appearing (rather than the mass storage drivers, which causes disconnection of the serial devices for some reason).

cat /etc/udev/rules.d/99-huawei.rules

SUBSYSTEM=="block", \
ACTION=="add", \
SYSFS{idVendor}=="12d1", \
SYSFS{idProduct}=="1003", \
RUN+="/sbin/modprobe usbserial vendor=0x12d1 product=0x1003", \
OPTIONS="ignore_device"

It now works with the vodafone python program and connects fine (in fact, I'm using it right now to file this bug).

The comment from the fiesty bug (addressing gutsy) found here:

https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/105545/comments/25

Works well to fix this problem, along with addressing it where it belongs (in HAL) and not udev.
