I tried to use the at "my pick for modem" - I can then get the stick to send SMS messages, but I cannot get it to recieve, when using gammu - any ideas ??

Well I must have messed something up. I started all over with a fresh installation of Raspian. Used your Message code and Voila! It works - the stick has switched to 12d1:155e and I see now three ttyUSB objects in the log.

Thank you very much

lsusb still shows 12d1:1f01 - no change

If I try this: usb_modeswitch -v 12d1 -p 1f01 -V 12d1 -P 14db -M '55534243123456780000000000000011063000000100010000000000000000' I get this response: Looking for target devices ... No devices in target mode or class found Looking for default devices ... found matching product ID adding device Found...

See my edit of the post. I forget to pull the power from the HUB where the stick is placed

Nothing in the extended log file ! No switching at all ??

No - no luck - no switching at all



The file /etc/usb_modeswitch.d/12d1:1f01 contains now:

# Huawei E353 (3.se)

TargetVendor= 0x12d1
TargetProduct= 0x14db

I have installed usb_modeswith on the raspberry with the command: apt-get install usb-modeswitch usb-modeswitch-data The Default id's og the stick are: 12d1:1f01 After installing the usb_modeswitch it is changed to 12d1:14dc - which according to this page: http://tjworld.net/wiki/Huawei/E3131UsbHspa...
