I think all the devices are unde /dev directory.
So if u want data from webcam u can just use /dev/video0.
In C u can use commaned like open,send ,recieve to send or recieve data

find  the appropriate file under /dev, find the base address of that particular port, if you can do that, then just use inb() or outb() according to your requirement. good luck!!
