Huawei E1550 USB Modem in 11.2

My machine is running on a dual-boot Windows Vista/openSUSE 11.2 scenario. I have been trying to get my Huawei E1550 to work on Linux for the past few days trying numerous methods suggested in other forums from people with the same problem, but I have not produced any fruitful results.

Plugging in the USB modem results in Linux detecting it as a CD-ROM. I have installed usb_modeswitch in attempt to switch it to a modem, but Linux still fails to recognize it. Windows Device Manager and lsusb both give ProductID=1001 and VendorID=12d1 connected to USB1. I’m guessing since Windows detects the correct IDs, the Linux versions should also be correct. In any case, I ran usb_modeswitch with the Default IDs for /etc/usb_modeswitch.conf, which gave 0x1446 as the ProductID, not 0x1001. Upon running usb_modeswitch, the product ID could not be found so the program fails and quits asking if it’s connected (and it is).

Just to test, I also ran wvdial which unsurprisingly did not detect the modem and could not send the init strings.

All commands were done using root privileges. Also note that when after usb_modeswitch is run and upon plugging in the USB, NetworkManager pops up near the tray saying “attached” but still shows the device as a CD-ROM.

Please help! My provider is Dialog and I am living in Sri Lanka if that is of any use.

I have same modem,and works but with some issues - sometimes OS does not recognize connection so must connect again.
After plugging modem in ,wait for icon to appear,then right-click network manager icon and go “edit connections”.There you will find “mobile broadband” tab and “auto mobile connection”,click on it and edit (rott pass will be asked at some time)
You must fill data for your provider !
After that I have problem that connection must be clicked twice to connect to net.
Cdrom will be shown allways, it will be useful to disable it - but how?

Had some unexpected luck…

The device now reads as a modem and is attached as /etc/ttyUSB0. I ran wvdial and it worked up to the point where it says:

warning, no nameserver found /etc/resolv.conf
Nameserver DNS failure, connection may not work

My Huawei device shows a solid blue color, which usually means it has a data connection, but when I open either Konquerer or Firefox the page cannot load.

Any ideas?

@serbianSuseUser: I have already attempted that but it will not progress beyond the point of “Activating”. wvdial this time actually made a connection but failed to produce a web page.

Finally managed to get it working… Funny. :stuck_out_tongue:

All I did following that error was echo “nameserver xxx.xxx.xxx.xxx” >> /etc/resolv.conf to state my DNS server and that was it. I think resolv.conf renews itself upon each connection, so making a script to add the nameservers into resolv.conf should fix each connection.

Thanks for reading. :smiley:

Can you post script here?
I also have that problem - connection is there,but no page can be opened

Actually, there is no need. /etc/resolv.conf does not renew itself upon each connection so just writing your DNS into resolv.conf should work.

In the terminal just type echo “nameserver xxx.xxx.xxx.xxx” >> /etc/resolv.conf where xxx.xxx.xxx.xxx is the nameserver’s IP of your provider. Alternatively, you can use wvdial to connect and it will print your provider’s nameservers for you.
