    Thumbs up Fedora 12, Huawei E220 problems

    There are some problems with the 3G modem from Huawei (mine is an E220 modem) on Fedora 12 with 2.6.31.5-127 kernel.
    First the modem is not mounted, I've got:

    Error mounting: mount: /dev/sr1 is not a valid block device

    ...or errors like this one.
    I've done some research on the web and I found the solution, which works :

    sudo rmmod usb-storage
    sudo modprobe usbserial vendor=0x12d1 product=0x1003


    where "0x12d1" = Huawei; and "0x1003" is my E220. You can get these from dmesg, look for lines like:

    usb 4-2: new full speed USB device using uhci_hcd and address 5
    usb 4-2: New USB device found, idVendor=12d1, idProduct=1003
    usb 4-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0
    usb 4-2: Product: HUAWEI Mobile
    usb 4-2: Manufacturer: HUAWEI Technologies


    Now, try reconnecting, if it still does not work then you might not have the DNS configured, so do this:

    sudo echo "usepeerdns" >> /etc/ppp/options

    (meaning that you have to add "usepeerdns" in the "/etc/ppp/options", this might be skipped).
    and reconnect, again.

    Cheers to all FEDORA users !

    I'm surprised you need to do this as my E169 just works. It has for a number of versions now. I plug it in and NetworkManager recognises it and I can connect.

    Your device differs from mine in the way that the kernel detects it as a different type of SCSI and the emulation is done....somehow different.

    Edit: read with more patience: ".....on Fedora 12 with 2.6.31.5-127 kernel......"

    Hello Valente.ro

    have a look at my recent post, where i describe my connection with my own huawei e220 with f12, 32-bit - I assume its the same kernel version as the one you are using.

    http://forums.fedoraforum.org/showth...10#post1295210

    I should mention that the firmware on my e220 was upgraded using the latest version, and a win xp machine to do it. the firmware version was necessary in order to make it work with Vista and Win 7.

    You can download the latest firmware from:

    Hi and thank you, but you got the issue wrong: is not a configuration problem but a kernel thing!
    The problem is due to a bug in the kernel version I've mentioned, I know very well how to configure this 3G modem both on any Linux machine and on Windows.
    By the way on my Windows Vista / 7 / XP I did not have any issues ever ! Strange that you had.

    Hi there, my Huawei e220 is about 2-3 years old (first batch sold retail), so the firmware had to be updated to work with vista and 7.

    The problem in F12 with the Huawei E220, of being unable to reconnect without unplugging and re-plugging the usb-modem, has been replicated on my machine with F12 with the ZTE MF626 modem as well. I saw in another one of your posts that this fix should be expected, at some point, in the updates - correct?

    Hi valente.ro

    I will, thanks. I'm not sure if my lack of expertise in F12 is upsetting you by stating obviously idiotic remarks. This thread started with your problems in F12 and the modem - problems which I didn't have with my own e220, so I suggest the firmware update. You also indicate to ozjd that the e220 and e169 are different somehow, since he doesn't have problems, so I indicate that there appears to be a re-connection problem in F12 with the mobile connections with TWO usb-modems, ZTE MF626 and the e220 - a problem which you have identified in the kernel itself. So, I assume we are all the happier for all this information. I find it useful. Thanks for your feedback.

    No you are not upsetting me, and no these are not idiotic remarks...as you've said. Just that this issue is not linked to the auto-reconnect thing. For my modem and others 3 or 4, on Fedora 12 the problem with the reconnection is not happening; that's why I've mentioned here, as a friend of mine find it too on Ubuntu that the problem is in the kernel. It might be also in the NetworkManager but, Ubuntu had the same issue on an older version of this app. So my opinion is that the kernel remains the only place where is could be the bug. Also, for Ubuntu there is an opened bug for this issue + a kernel patch which, both, I'm waiting to have in our wonderful Fedora. I'll not give up on this distro just because an error. Now, don't hurry to judge people, just have the patience to read ...twice or more the thread. Is just a solution that i'm proposing

    Edit: -- feel free to ask me about Linux (Fedora specially) any issues that you might get.

    Hi Valente.ro

    The issue experienced on my end is a manual disconnect, and then trying a manual reconnect - not auto-reconnection.

    If you can , please have a look at
    http://forums.fedoraforum.org/showthread.php?t=234541

    they are having problems with a reconnect in F12 with an ADSL connection, while the problem is not in ubuntu 9.10 with kernel 2.6.31-14

    Just a thoght? What if the problem is in the NetworkManager in F12? supposing the kernel is okay - is there a fix for this? what can I try?

    Thanks again

    the issue, yes, can be in the NetworkManager since they did many modifications in it. For the moment i don't know for a fix since i'm not getting this issue........yet; and i did not need to look for it.

    this is probably not a problem with device driver rather how to configure a connection profile.
    I'm trying to use huawei e1550 USB modem to connect to my provider's GPRS network. on FC10 I need the usb_modeswitch to recognize the device. no such problem with FC12.

    when using wvdial I have to manually add the name servers into /etc/resolv.conf which is very un-elegant, but it works.

    my problem is using networkmanager I can connect to network but can only ping by IP address. no name resolution whatsoever. I'm not a linux newbie, but for networking I usually took them for granted so I've very little experience with network configuration scripts. how can I connect to mobiledata using networkmanager? if not how can I do it with wvdial elegantly?

    This is very curious.
    I have a Huawei E220 and also I'm not able to use it with a fresh Fedora 12 in a Toshiba Satellite A100 (with a NVIDIA graphic card). It doesn't mount, outputs some errors, and is not able to connect to internet. When it does it usually lasts a few seconds before it goes down.
    But in another laptop (HP Pavillion zv5490EA, with a ATI graphic card), also with a fresh Fedora 12, it runs flawless. It mounts the disk and connects normally.
    I'm confused about it.
    The distro is the same, the kernel version the same, the Huawey modem is the same, but it behaves diferently.
    Only the hardware is different (USB? Graphic card?)
    If it's a kernel bug, as it seems to be, why the bug doesn't occur in HP Pavillion laptop?
