Vodafone 3G Dongle (Huawei K3772) working on Slackware.14.0

Using the information available at I have successfully connected and used this dongle with my Slackware.14.0 installation.

For the impatient, use lsusb to ensure that you dongle is recognized by you system, something like:

Bus 002 Device 003: ID 12d1:1526 Huawei Technologies Co., Ltd.
should be displayed. Use the HEX codes as in 12d1:1526 to feed the following command:

usb_modeswitch -v 0x12d1 -p 0x1526 \
               -V 0x12d1 -P 0x1c05 \
                -s 20 \
                -M "55534243123456780000000000000011060000000000000000000000000000"
If all went well, a lsusb should display something like:

Bus 002 Device 004: ID 12d1:1c05 Huawei Technologies Co., Ltd. E173s 3G broadband stick (modem on)
The last remaining step is to use sakis3g to actually use the dongle. Since the seems to not be available, I used the sakis3g.tar.gz found at

I have also made available the version of sakis3g THAT WORKED FOR ME(TM) at the following locations (at pastebin, split at six parts):

Part 1 :
Part 2 :
Part 3 :
Part 4 :
Part 5 :
Part 6 :

Happy browsing!
