I have tried to connect an external webcam to my laptop to take video feed from that. At first i faced some problem but when i dig i found a solusion.
I wrote "imaqtool" command in the command window of matlab and select my desier webcam and resulation.
If someone is faceing this kind of problem, he/she can try this.
