Do xawtv -hwscan and see if you get any output. If its doesn't pick up a device then the cam may not be correctly configured.

Hi
thanx my problem is solved.when i gave
#xawtv -hwscan
This is xawtv-3.94, running on Linux/i686 (2.6.9-prep)
Warning: locale not supported by Xlib, locale set to C
looking for available devices
when i connected webcam n gave
# xawtv
it started working

To check if ur driver is installed properly connect the cam n try
#dmesg | grep cam-name
if u think drver is installed properly n there r no errors
try
#lsmod
in that u should be able 2 find ur cam
if not in ur root directory in the .bash_profile in the end add the following command
modprobe -v cam-name
now check lsmod and then dmesg
now if ur driver is installed properly should b able 2 see ur cam
if evrythngs fine connect ur cam n try xawtv
