I am currently working on a project and I am trying to load the kernel from usb instead of an sd card. How do you configure u-boot to support usb commands?

Why don't you attempt to please read the documentation first? Try
"CONFIG_CMD_USB" for starters.

You also need to enable driver for your USB host controller.
