USB_ModeSwitch

Hello everybody!
I can't find subj in the list of devices. I'm a noob and I don't understand what I need to do.
Please help!

The easiest way is to copy an existing config file like "12d1:1583", put it in "/etc/usb_modeswitch.d" and change the name to "12d1:1591".

That should make the modem switch the next time you insert it. To check if it worked, either run the "dmesg" command line tool repeatedly or enable usb_modeswitch's logging in "/etc/usb_modeswitch.conf" (with a text editor).

Once you know the "target" USB ID you can adapt it in the "12d1:1591" file, by using a simple text editor.

This may not be the best place to ask but does anyone know if it's possible to disable the CD mode in the modem permanently? I'd like to use this in my router (Billion) but the dongle seems to remain in CD mode when connected. I did see some old comments for serial modems about AT commands to change this behaviour but this doesn't seem possible with the K5161.

If this is a K5161h with the USB Id 12d1:1591 then I suspect that it is already switched.
What does the cmd lsusb tell?
