    Re: modem-manager not working

    Alexfish,

    I did as you have suggested. I am displaying the output of 'tail -f /var/log/syslog'. There is a line in the middle. It signifies the instant after which I plugged the modem.

    Re: modem-manager not working

    looks like mtpbrobe having a look at the device first, for me this is a new one

    Looked at, possible mtp-probe may be part of mtp-tools , for media transfere

    if the probe is holding the device then it could be a problem

    suggest look at the System Monitor to see if a daemon is running , RE apart of the mtp-tools

    if there is suggest killing the daemon , can do that from the System monitor

    or from the terminal

    Code:
    sudo killall <name of daemon>
    also check and see if there are two instances of udev running

    can also suggest dissable usb_modeswitch

    Code:
    sudo gedit /etc/usb_modeswitch.conf
    edit the line
    Code:
    DisableSwitching=0
    to
    Code:
    DisableSwitching=1
    save and exit

    after the probing , wait a while then issue the usb_modeswitch command , have already posted how to do this.

    see what happens

    regards

    Re: modem-manager not working

    Alexfish,

    I tried to look for mtp daemon as you suggested. But I could not find any such process in the system monitor. I tried it on the terminal as well:
    $ ps -ef|grep mtp
    sath 3518 3219 0 17:32 pts/0 00:00:00 grep --color=auto mtp
    I could not find any such process. I have attached log from the output of the command, 'ps -ef'.

    Next, I wanted to execute the other steps mentioned in your post. But I was not clear on one thing: Do you still want me to disable usb_modeswitch, probe it and issue usb_modeswitch command? I am asking this as I was not sure if this is related to mtp probe daemon or unrelated to it.
    If they are not unrelated, then I will execute these steps.

    Thanks

    Re: modem-manager not working

    Alexfish,

    Continuing with my previous reply, I executed the other steps as well. First I edited, /etc/usb_modeswitch.conf and set DisableSwitching=1. Then I plugged the usb modem, "12d1 1446". The output of usb-devices for this device after plugging the device is as follows:

    T: Bus=03 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 3 Spd=12 MxCh= 0
    D: Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
    P: Vendor=12d1 ProdID=1446 Rev=00.00
    S: Manufacturer=HUA˙WEI TECHNOLOGIES
    S: Product=HUAWEI Mobile
    S: SerialNumber=˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙˙
    C: #Ifs= 1 Cfg#= 1 Atr=a0 MxPwr=500mA
    I: If#= 0 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=usb-storage
    So I can see that the driver is set to usb-storage. Next, I tried to switch the usb modem using the command you suggested previously on the terminal. But surprisingly, it is giving an error. The output is as follows:

    $ sudo usb_modeswitch -v 0x12d1 -p 0x1446 -M "5553424312345678000000000000001106000000000000000 0000000000000"

    Re: modem-manager not working

    Hi

    Not sure what is happening , I have not install 12.04 as of yet.

    Yet Last reports I received , indicated that the Device ID 12d1,1446 worked in both modes . See last page
    How To : Mobile Broadband Connections [ Ubuntu 11.04 : 10.10 : 10.04 : 9.10] ( 1 2 3 ... Last Page)

    Please Note this Tutorial is now closed.

    on Ubuntu 12.04 , but now wondering if there is diff between 64 bit and 32 bit systems

    can post if system 32 or 64 bit

    I do know some devices may work with a different message , this will not implement the ethernet type interface $g mode, present on newer devices , sakis3g ,usually gets them working in the 3g mode, but still operate at the faster speeds (4g) of the standard 3g method of connecting.

    So,
    from what I am seeing , best advice , Visit the usb_modeswitch forum.

    They may advise installing usb_modeswitch from source , IE , compile it ,for and on your
    system , It is easy to do, even for a novice ,also Josh is very helpful , but not in a direction,
    where usb_modeswitch scripts have been adapted to suit some systems, the main one
    for some Ubuntu versions , could be the lack of tcl ,

    regards

    Re: modem-manager not working

    Alexfish,

    I am currently running 32 bit version of ubuntu 12.04.

    I will ask the same query at usb_modeswitch forum. Let me hope for the best!

    In the meantime, I will also try to get hold of a system that has 11.10 (since I know that it works perfectly well on that system). I will see the output of /var/log and compare it with the output in 12.04 when I plugin the usb modem.

    sad that Ubuntu isn't issuing a permanent fix for this irritating problem. I had to switch to Fedora where this problem with 3G dongles does not exist.

    Hi surga

    I am not sure if this a specific as in "Ubuntu" , if it were , then I would have presumed to have seen a lot more , "Can't Connect" , Threads ,

    Lets see what the out come is between the two version + the out come , if any, via usb_modeswitch forum

    Re: modem-manager not working

    Surja,

    Yes, I know it can be frustrating. Strangely, this modem was working well on ubuntu 11.10. But somehow it stopped working on ubuntu 12.04.
