3G HSDPA USB Modem detected as CD Drive

[kadal27]

I am trying a 3G HSDPA USB Modem inUbuntu 10.04.
It detects it as a CD Drive.

When I tried to 'Safely Remove Drive'
I got the following error:

Unable to stop drive
Error detaching: helper exited with exit code 1: Detaching device /dev/sr1
USB device: /sys/devices/pci0000:00/0000:00:1d.2/usb4/4-2)
SYNCHRONIZE CACHE: FAILED: No such file or directory
(Continuing despite SYNCHRONIZE CACHE failure.)
STOP UNIT: FAILED: No such file or directory

Output of lsmod |egrep “usb|option” is as follows:

usb_storage 39425 0
option 15654 0
usbserial 33019 1 option

Output of 'lsusb'

I searched, read and tried several guidances from several forums, blogs etc. Some of the outputs are mentioned above. But still I can't detect and use my modem.

Please help me.

(Make of the modem not known)

[halj32]

try installing usb-modeswitch + usb-modeswitch-data
then you should see the dongle in your network manager
then you just have to enter (if in UK)
go to edit connections, mobile broadband, new connection,
give your network a name ie; 3G
Number; *99#
APN: 3internet
done
enjoy

[kadal27]

Hi halj32,
I've already tried but no use.
Network manager does not detect the modem.

For information, I'm from India.

[alexfish]

hi

just try eject device , see what happens

[kadal27]

Hi alexfish,
I've already tried it also, but nothing happened

I used
sudo eject sr1

It came back to prompt without any action or error message!
That CD Drive is also staying there!!

[alexfish]

hi

checking the messages shows the driver but there are no ports registering
so it's shooting in the dark time.

have you tried
register the device in windows , if so , did it work

if worked in windows , try in windows again, does it work

if not registered in windows , try registering the device in windows

make sure the device works in windows then try in ubuntu

once with the device plugged in at boot , see if it works

once after boot , see if it works

just leave any devices showing on the desktop

in both cases post the listing of these commands from the terminal

Code:

lsusb -t

Code:

ls -al /dev/serial/by-id/usb*

if it comes up with an error try

Find the Mass Storage of the device pick only one of these to post

Code:

ls -al /dev/disk/by-id/usb*Mass_Storage*

or

ls -al /dev/disk/by-id/usb*Storage*

or

ls -al /dev/disk/by-id/usb*

can also suggest to remove usb_modeswitch , but not totally remove

Hi alexfish,
It worked and works fine in Windows (XP).
In Ubuntu I already tried both attaching before and after boot and there is no difference.

Output when attached after boot:

On my 3G USB modem, the flash drive part contained both windows and Linux drivers, to be manually installed by the user. Is this the case here?

[alexfish]

Hi Kadal

Can you install Sakis3g , this is a 3g manager, this may or may not work , but it as a logging
facility , also more in control of the modeswitching

How to install latest version in Ubuntu: . Possibly Sakis3g 0.2.0e . now includes usb_modeswitch " Version 1.1.3 (C) Josua Dietze 2010"

leave the existing usb_modeswitch uninstalled

From the terminal:
Codes:

sudo bash

cd /usr/bin

wget 'http://www.sakis3g.org/versions/latest/sakis3g.gz'

echo "dda70fd95fb952dbb979af88790d3f6e sakis3g.gz" | md5sum -c

You should see: sakis3g.gz: OK

Codes:

gunzip sakis3g.gz

chmod +x sakis3g


then run sakis3g from the terminal

Code:

sakis3g


Have a look through the menus , and try the options from the menu , it won't harm your system

also could you post detail of

CODE:

uname -a

alexfish

Hi alexfish,
It worked fine,
on both by desktop and netbook.
Thanks a lot.

Output (from my desktop) for uname -a

Once again thank you so much!
