USB to LAN does not work

my PC has 2 LAN cards
1) to connect to the internet gateway(via tataindicom)
2) to connect to my other PC thru cross wire

the above 2 work fine.

now i need to connect my PC to my bro's laptop.
I purchased a "USB to LAN" device and a cross wire cable.
thru this i connected my PC to my bro's lappy.
immediately the "USB to LAN" device and LAN in my bro's laptop glow to show they are connected and the device n wire are working fine.

i set ip addresses to both the LAN cards 192.168.0.2 (PC) and 192.168.0.35 (laptop). default gateway and DNS for the lappy as 192.168.0.2 .

whn i ping there is no response frm either side. DISABLED firewall. still no response.
any idea wat the reason is??? :-|

If ur seeing both the lan connection in LAN connection setting than u need to bridge the two connection.

i dont keep all machines on all the time ...
it doesnt allow me to bridge the connections. why do you say i will need to bridge the connections??

any help anyone?
