HUAWEI K3771 and setup of modeswitch

Hey,
I have currently Ubuntu 11.04 and a 3G dongle HUAWEI K3771.
I am sure you will find my question naive but anyway :
I downloaded usb-modeswitch-1.1.8.tar.bz2, then unpack it. I go into the directory and then I type sudo make install :
romain@blabla:~/usb-modeswitch-1.1.8$ sudo make install
install -D -s --mode=755 usb_modeswitch /usr/sbin/usb_modeswitch
install -D --mode=755 usb_modeswitch.tcl /usr/sbin/usb_modeswitch_dispatcher
install -D --mode=755 usb_modeswitch.sh /lib/udev/usb_modeswitch
install -D --mode=644 usb_modeswitch.conf /etc/usb_modeswitch.conf
install -D --mode=644 usb_modeswitch.1 /usr/share/man/man1/usb_modeswitch.1
install -d /var/lib/usb_modeswitch
romain@labla:~/usb-modeswitch-1.1.8$
I have got just these lines but I don't think that anything has been installed. And I go in Synaptic, I see that there is the version 1.1.7-1 installed on my computer.
Can you tell me what is the problem here?
Thank you for your answers!
Romain

If you install any program from source, the package manager will not know about it. But the files are updated anyway. Run "sudo usb_modeswitch -h" and you should see version 1.1.8. I believe there are no conflicts as long as you don't update with Synaptics to an older version than what is really running.
I just recommend checking the folder "/lib/udev/rules.d". There should be only one
"<..>-usb_modeswitch.rules" file. If there are two, rename "40-usb_modeswitch.rules" to the other name, overwriting that file.
Note that the device info is contained in the data package, so you want to update that too.

Thank you for answer Josh.
I checked the folder "/lib/udev/rules.d" and there is only one "<..>-usb_modeswitch.rules" file, which is actually "40-usb_modeswitch.rules".
But the modem is still recognized as a CD.

So, did you update the data package?

Yes I did :
romain@blabla:~/usb-modeswitch-data-20110714$ sudo make install
install -d /usr/share/usb_modeswitch
install -d /etc/usb_modeswitch.d
install -D --mode=644 40-usb_modeswitch.rules /lib/udev/rules.d/40-usb_modeswitch.rules
install --mode=644 -t /usr/share/usb_modeswitch ./usb_modeswitch.d/*
if [ -f /etc/issue ]; then \
UDEVADM=`which udevadm 2>/dev/null`; \
if [ "x$UDEVADM" != "x" ]; then \
UDEVADM_VER=`$UDEVADM -V 2>/dev/null`; \
if [ -z $UDEVADM_VER ]; then \
UDEVADM_VER=`$UDEVADM --version 2>/dev/null`; \
fi; \
if [ $UDEVADM_VER -gt 127 ]; then \
$UDEVADM control --reload-rules; \
else \
$UDEVADM control --reload_rules; \
fi \
elif [ `which udevcontrol 2>/dev/null` ]; then \
`which udevcontrol` reload_rules; \
fi \
fi

O.K., so you plug your stick and nothing appears to happens.
Did you check with "lsusb" and "dmesg"? It's not unusual for Huwaei devices to expose the install "CD" again after switching. Then you end up with several serial ports, a micro SD card slot plus the original pseudo CD-ROM.

Yes, I plug the stick and nothing happens.
However, the result of "lsusb" seems to indicate that the switch was done.

Your assumption is correct: the switching worked, the driver is bound and the serial ports are ready.

So what i have to do make it work?
Because it doesn't work with VMC and neither with Network Manager.
Posted: 08 Aug 2011, 16:19

Well, I recommend asking the developers of these programs, probably filing bug reports. I know that people from Network Manager are interested in such reports.
See the main doc page of usb_modeswitch (link above), paragraph "How to use", about possible replacements for NM.

It works with Sakis3G.
Thanks for you answers!
