lsusb gives me the following information
Bus 005 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 002: ID 0ac8:301b Z-Star Microelectronics Corp. Sansun 
SN-510 Web Cam [hv713d]
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 003: ID 049f:0004 Compaq Computer Corp.
Bus 001 Device 001: ID 0000:0000

The webcam is listed with sensor type as hv713d whereas when i checked 
in windows in the documentation steps there for the zc*.sourceforge.net 
project (thru regmon) the sensor type listed in the registry was hv7131b

hv7131b is listed in the page but not hv713d, so i shall try loading 
spca5xx.

i gave the following commands
corporal at hellocpu:~$ sudo modprobe -r zc030x
Password:
FATAL: Module zc030x not found.
corporal at hellocpu:~$ sudo modprobe -r zc0301
FATAL: Module zc0301 not found.
corporal at hellocpu:~$ sudo rmmod zc0301p
ERROR: Module zc0301p does not exist in /proc/modules

Infact /proc/modules itself does not exist when i checked in Nautilus.

I gave the first sudo modprobe command but there was no reaction/output 
from the system

The last few lines of kern.log are as follows. i can't seem to find 
anything.

Then i gave the 2nd sudo modprobe command (sudo modprobe videodev) and 
still no change in kern.log

You will have to help me. I don't know what is the model, vendor or 
product id -- is it z-star microelectronics corp, and product id as 
0ac8: 301b?

I have 2 reports on sensors (windows regmon detects it as hv7131b 
whereas lsusb in ubuntu detects it as hv713d) Bridge information I don't 
know how to find.

Thanks a lot. Am still trying to get this to work. The snoopypro 
software in windows ME was buggy. I could not get it to work after 
following the instructions  -so can't say what the bridge is.
