Using Huawei e1550 with a Thinkpad x60 on 3 UK

2011/05/24

The Huawei e1550 3G dongle works beautifully with Linux. One annoyance is that it contains a CD image which confuses Linux. In order to make it work we just need to use usb_modeswitch. First plugin in the dongle, and then run the following command:


usb_modeswitch -v 0x12d1 -p 0x1001 -H 

The argument to -p may be different for you: check the output of lsusb -v and find the product number in the output. Having got Linux to recognize the modem, you now need to configure wvdial. I use pay-as-you go on 3 UK. My wvdial.conf is as follows:


[Dialer Defaults]
Init1 = ATZ 
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 
Stupid Mode = 1
Modem Type = Analog Modem 
ISDN = 0 
Phone = *99# 
Username = username
Password = password 
Modem = /dev/ttyUSB0 
Dial Command = ATDT Baud = 9600 
[Dialer three] 
Init2 = ATZ 
Init3 = ATQ0 V1 &D2 &C1 S0=0 +IFC=2,2
Init5 = AT+CGDCONT=1,"IP","3internet" 
ISDN = 0 
Modem = /dev/ttyUSB0
Modem Type = Analog 
Modem Baud = 460800 

Then run wvdial: wvdial -C wvdial.conf three and you should be connected!
