Hi, All

Trying to connect to the web by using sakis3g I got a message "failed to connect" After I had read USB_ModeSwitch documentation, they say user should run "eject" to correct the problem...that´s it! How shall I do this? What syntax? Shall I add some text to /etc/udev/rules.d? What file?

Why not just install the usb-modeswitch and usb-modeswitch-data package?

AFAIK sakis3g will work fine with a modem that's already switched.

All kay, usb_modeswitch is installed...what to do in order to connect the web?

If you see 19d2:0031 when you run "lsusb", you can start sakis3g.

When I type "lsusb" the modem ID is 19d2:0091 not 19d2:0031!

Hmm, I assumed from your first post that your device is switching from 19d2:2000 to 19d2:0031.

Anyway, your device is in modem mode. There is no guarantee that sakis3g will recognize it, I think there was no update for a long time. If it doesn't work, you may have to try other programs for connecting.

Maybe enabling its ID (19d2:0091) to the kernel and recompiling it..I will try kernel-3.0.8

The usb_modeswitch package will enable the serial driver if it does not bind automatically.

Check if you get "ttyUSB" ports after switching (run "dmesg"). If so, you need to find the right one. There should be a symlink to that port provided by usb_modeswitch. Look for "/dev/gsmmodem".

All kay, modem resides at /dev/ttyUSB3 and I didn´t locate any gsmmodem file at /dev

Hi, Everybody

I´m trying to put to work ZTE MF636 modem but I get somewhat harassed when editing /etc/usb_modeswitch.conf

##ZTE MF636
DefaultVendor=0x19d2
DefaultProduct=0x2000
MessageEndPoint=????????
MessageContent=?????????

Some more options?????

Please, tell me where to find these serial of numbers (????)

You must have a very old version of usb_modeswitch ...

No need to configure anything with a more recent version. Did you read "How to install" on the main doc page?

19d2:2000=>19d2:0091

I´ve followed all your installation instructions and device was unable to connect with sakis3g. It´s interesting 19d2:0091 is at rules files (target) but even adding any rule to /etc/usb_modeswitch.conf it fails connecting or shall I add the rule to /usr/sbin/usb_modeswitch.d? My version of usb_modeswitch is 1.2.0

As I said, sakis3g is a bit old (it seems not to be maintained anymore).

If you can see the ttyUSB ports, you should be able to use the modem with any connection software.

Please do not try to tweak the original files from usb-modeswitch and usb-modeswitch-data packages. This will not help in your case.
Your device is supported, and if you see product ID 0091 and the ttyUSB ports, usb_modeswitch has done its job. It has nothing to do with the actual connection.
