So, I have a problem with the modem Huawei E1550,when I turn on laptop the icon appears that there is a modem, and sometimes not, plug and play like it is crashing, I have to restart my laptop and then to pray to God to appear icon for conection
Are you using openSUSE 11.2 or 11.3? E1550 has got a virtual CDROM in it and sometimes it is being recognized and the modem is ignored. In 11.3, it eventually finds the modem. For more info, read the following:
Draisberghof - Software - USB_ModeSwitch
Ok, I read a few days ago but that does not solve the problem, one thing is for sure a problem exists and I do not know how to solve it.
Did you have a look at the log to confirm that the problem is due to the detection of the virtual CDROM?

But now I got NETWORK MENAGMENT DISABLED???
Plug in the modem after executing the following command and then, see the messages:

Question: Did you install usb_modeswitch?
(version 1.1.3 is in the repositories)
when you get
ID 12d1:1001 Huawei Technologies Co., Ltd. E1550 USB Modem
that should mean the device is recognised as a modem;
the usb_modeswitch programme aims to switch the mode of the usb_device from CD_ROM to modem
so if lsusb says 1001, the device should be switched
syampillai has been helping, and suggested a command to you
another that can be useful is
dmesg | grep tty
If you copy and paste this into a terminal, it should show a ttyUSB0 response, confirming the device is ready
No, I didn’t because they do not understand instructions how to install
Recommendation:
copy and paste this command
dmesg | grep tty
into a terminal;
It may help decide if you need to install usb_modeswitch
Suggestion: copy and paste your result back here please
dmesg gives nothing and grep tty gives very long log file
I believe you misunderstand me again
when I paste this command
dmesg | grep tty
into a terminal (without a Huawei plugged in)
here is what I get
dmesg | grep tty
0.001344] console [tty0] enabled
0.842917] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
0.843295] 00:08: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
I do NOT have a Huawei plugged in, otherwise I would like get a ttyUSB0 response
I was urging you to copy and paste the command into a terminal
the command would help us see if your device is recognised as a modem
Oh, I typed separately:(
This is what I got 0.000000] console [tty0] enabled
so seems your device is currently not seen as a modem;
so you need to install usb_modeswitch
if you go to YaST; software; type in usb_modeswitch and it should be findable from the repos;
equally, some more seasoned warrior may recommend a zipper up usb_modeswitch command that might save opening YaST?
OpenSuse offer the 1.1.3 version as a rpm so easily installable on OpenSuse
I installed this version of usb_modeswitch on an Eee running gnome opensuse 11.3 recently and it has managed the E1552 modem well
As recommended by pdc_2, install usb_modeswitch.
su
zypper install usb_modeswitch
zypper update
This will also update it to the latest version (there was some recent updates to support more devices).
su
zypper install usb_modeswitch
zypper update
great; many thanks
thank you, finally works:)
well done syampillai
How do you install it if you don’t have connection to the Internet?
I believe this thread applies to my problem which I also yesterday described here: https://forums.opensuse.org/newreply.php?p=2563660&noquote=1
