I'm runnig Ubuntu Karmic too, so I have the same problem, but found an ugly workaround:
First i use usb_modeswitch as stated in many places: > sudo usb_modeswitch -v0x0fce -p0xd0e1 -O 1 Then I try to connect using wvdial, it doesn't work, but somehow it seems to initialize the MD400 (a blue lamp starts blinking) > wvdial I use the following /etc/wvdial.conf : ---START--- [Dialer Defaults] Init1 = ATX3 Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 Init3 = AT+CFUN=6 Init4 = AT+CGDCONT=1,"ip","internet.sonofon" Phone = *99# Modem Type = USB Modem Baud = 460800 New PPPD = yes Modem = /dev/ttyACM0 ISDN = 0 Password = '' Username = '' ---END--- Note: Modem = /dev/ttyACM0 have to be changed to whatever your device is ttyACM1, ttyACM2,... or even ttyUSB0,... I don't what other part of the file might be important, it just worked for me. After that the network manager can connect using the default settings. Note: you have to run the two lines above every time you plug in the stick or restart the system. As mentioned, I think the problem occurs somewhere in the initialization of the modem, but cant say where precisely, as this fix was more luck then something else...
