webcamera access with ML310

I am using ML310 in STANDALONE along with usb based Quickcam
expreess(Web camera) for my project on real time image processing.

I came to know that it is possible to access the usb port of the board
using the linux kernel.
I am interested in accessing the port to recieve the data(frames) from
my webcamera and transfer the contents into the Bram.

Any help in this regard would be of utmost help.
