Reliance Netconnect USB card on Linux - Howto 
============================================= 
The following worked for me on Ubuntu amd64 but should work 
for all the distros. 
Execute everything as root 
Check your card is recognized by the kernel 
Code: 
# cat /proc/bus/usb/devices 
..... 
..... 
T:  Bus=02 Lev=01 Prnt=01 Port=05 Cnt=02 Dev#=  4 Spd=12  MxCh= 0 
D:  Ver= 1.01 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=16 #Cfgs=  1 
P:  Vendor=12d1 ProdID=1001 Rev= 0.00 
S:  Manufacturer=Huawei Technologies    
S:  Product=Huawei Mobile                  
S:  SerialNumber=HUAWEI EC3X1 
C:* #Ifs= 2 Cfg#= 1 Atr=e0 MxPwr=100mA 
I:  If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=pl2303 
E:  Ad=81(I) Atr=03(Int.) MxPS=  16 Ivl=128ms 
E:  Ad=8a(I) Atr=02(Bulk) MxPS=  64 Ivl=0ms 
E:  Ad=0b(O) Atr=02(Bulk) MxPS=  64 Ivl=0ms 
I:  If#= 1 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=pl2303 
E:  Ad=83(I) Atr=02(Bulk) MxPS=  64 Ivl=0ms 
E:  Ad=06(O) Atr=02(Bulk) MxPS=  64 Ivl=0ms 
..... 
..... 
Now modprobe the driver 
Code: 
# modprobe usbserial vendor=0x12d1 product=0x1001 
Should get something like this with dmesg 
Code: 
# dmesg 
[ 2315.412106] usbcore: registered new interface driver usbserial 
[ 2315.412508] drivers/usb/serial/usb-serial.c: USB Serial support registered for generic 
[ 2315.461938] usbcore: registered new interface driver usbserial_generic 
[ 2315.461945] drivers/usb/serial/usb-serial.c: USB Serial Driver core 
[ 2315.480382] drivers/usb/serial/usb-serial.c: USB Serial support registered for pl2303

[ 2315.480691] usb 2-6: pl2303 converter now attached to ttyUSB1 
Now edit your wvdial.conf file 
Code 
# vi /etc/wvdial.conf 
[Modem0] 
Modem = /dev/ttyUSB0 
Baud = 115200 
SetVolume = 0 
Dial Command = ATDT 
Init1 = ATZ 
FlowControl = Hardware (CRTSCTS) 
[Dialer cdma] 
Username = You Phone Number Here 
Password = Your Password ... usually same as your phone number 
Phone = #777 
Stupid Mode = 1 
Inherits = Modem0 
Now run wvdial 
Code: 
# wvdial cdma 
--> WvDial: Internet dialer version 1.56 
--> Cannot get information for serial port. 
--> Initializing modem. 
--> Sending: ATZ 
ATZ 
OK 
--> Modem initialized. 
--> Sending: ATDT#777 
--> Waiting for carrier. 
ATDT#777 
CONNECT 230400 
--> Carrier detected.  Starting PPP immediately. 
--> Starting pppd at Sat Mar  3 22:55:20 2007 
--> Pid of pppd: 24314 
--> Using interface ppp0 
--> local  IP address 220.226.50.126 
--> remote IP address 97.239.2.10 
--> primary   DNS address 202.138.103.100 
--> secondary DNS address 202.138.96.2 
Thats it ... you are now connected 
Ensure that your internet traffic goes through your "Modem" 
In Ubuntu ... this can be done @ System->Administration->Networking 
Enjoy ) 
Dunno how to make this sticky ... if anyone can, please do it
