modem-manager not working
Just installed my 12.04 and had restored backup from the 12.04 beta-2 version i was using previously. now my modem is not been detected by ubuntu. Previously it was never a problem(till 11.10). tried to use a third party software "sakis3G". it also didn't worked out(segmentation fault and core dumped). in the beta-2 also, it had problems sometimes but "sakis3G" would have connected to the internet easily. Now it's not working. Please Help!!!
Re: modem-manager not working
from a fresh cold boot , allow time for the system to settle , then plug the device
from the terminal
Code:
ls -al /dev/serial/by-id
Re: modem-manager not working
still not working.
what are the commands for?
the first one produced a lot of information.
second one there was no such folder.
should i post the output of first one.
Re: modem-manager not working
how to find the device :
first use lsusb command
it shows a result like
Code:
Bus 002 Device 002: ID 0603:00f2 Novatek Microelectronics Corp.
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 006: ID 12d1:14ac Huawei Technologies Co., Ltd.
Bus 001 Device 003: ID 059b:047a Iomega Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
from this info I know the device is
Code:
12d1:14ac Huawei Technologies Co., Ltd.
the usb-devices command , look for block information with the device id's , highlighted
Code:
T: Bus=01 Lev=01 Prnt=01 Port=02 Cnt=02 Dev#= 6 Spd=480 MxCh= 0
D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
P: Vendor=12d1 ProdID=14ac Rev=00.00
S: Manufacturer=Huawei Technologies
S: Product=HUAWEI Mobile
C: #Ifs= 6 Cfg#= 1 Atr=c0 MxPwr=500mA
I: If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
I: If#= 1 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=option

I: If#= 5 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=usb-storage
then post the info , like so
Remember the above is an example , and will explain what the commands do later

Re: modem-manager not working
That be the device , buts has no drivers attached , can try load the driver and ensure the device gets entered in the new id , if not recognise by the driver
these commands may load the driver
open up the terminal and enter root
try the usb-devices command
if the driver has not loaded after that command ( let me know if it has or has not) try this ,
this command may load the device into the new id
Code:
echo 1C9E 9605 > /sys/bus/usb-serial/drivers/option1/new_id
then check the results with the usb-devices command
if this works will post details on how to ensure the drivers loads each time the device is plugged in
Re: modem-manager not working
applied both the methods.
first time it showed the modem and i was able to connect to the internet. then restarted the machine. it does not show the modem now again.
Re: modem-manager not working
redo the commands as listed , does it show ,
Also post results of the Device from the terminal
It Don't show , means nothing From where I sit...

With your permission, I ought to join this thread.
I have a similar case, though I have a different modem. The drivers were loaded and I can connect to the internet, but it does not retain; I have to enter the same commands whenever I plug the modem. Can you please post how to load the drivers every time the modem is connected.
Thanks in advance.
