CentOS - Mar 2011 - reliance netconnect as on a Linux system ( centos5.5 ) Modem not responding.

Hi

I am trying to connect a reliance netconnect data card on my linux box (
cent os )  , i am able to the detect the device /dev/ttyUSB0

these are the following steps I did :

Check your card is recognized by the kernel
# cat /proc/bus/usb/devices

.....
.....
T:  Bus=07 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#= 11 Spd=12  MxCh= 0
D:  Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs=  1
P:  Vendor=19d2 ProdID=fff5 Rev= 0.00
S:  Manufacturer=ZTE, Incorporated
S:  Product=USB Storage
S:  SerialNumber=000000000002
C:* #Ifs= 1 Cfg#= 1 Atr=c0 MxPwr=100mA
I:  If#= 0 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50
Driver=usbserial_generic
E:  Ad=89(I) Atr=02(Bulk) MxPS=  64 Ivl=0ms
E:  Ad=0a(O) Atr=02(Bulk) MxPS=  64 Ivl=0ms

i use the usb_modeswitch to detach it as a storage dev and attach it to a
usb dev


usb_modeswitch -v 0x19d2 -p 0xfff5 -d 1  19d2:fff5

usb_modeswitch -v 0x19d2 -p 0xfff5  -H 1


now i modprobe the usbserial


modprobe -v -r usbserial

modprobe -v usbserial vendor=0x12d1 product=0x1001


now do I do  a dmesg

i edit the vi /etc/wvdial.conf with the following content

Sorry, no modem was detected!  Is it in use by another program?
Did you configure it properly with setserial?

Please read the FAQ at http://open.nit.ca/wvdial/
