By "linux 7.0" I'm assuming you mean Redhat linux 7.0? You'll need to load a kernel module (linux speak for a hardware driver) for your camera. There is a module for kodak cameras using a usb connection, and you'll also need to load the right usb module for your motherboard.
Have a look in /usr/src/linux/Documentation/usb/dc2xx.txt for info on the camera driver, /usr/src/linux/Documentation/modules.txt for info on using modules and
http://www.linux-usb.org for more linux usb info. If you can't find any of these docs then you need to install the kernel-source rpm that matches the kernel you are using from the linux cd(s). If the camers does not connect with usb then you need to tell us what it uses.
