Plug your USB device into the RoboRIO's USB Port like so:

Run the command "dmesg" and find out where the device is assigned (Example: /dev/sda).

You may need to setup a swap filesystem on the device. If you do then use fdisk (Example: "fdisk /dev/sda") to clear the existing partition table on the device and assign a clean partition of type Linux Swap (82) to the device's new partitions.  In our case, after deleting the existing partition table and then creating a new partition (/dev/sda1).

You can then use mkswap on the device: "mkswap /dev/sda1".  This sets up a swap area on the device.

You can then use swapon to enable the OS that the swap space is available to use (Example: "swapon /dev/sda1").

You can also use swapoff to disable the swap space (Example: "swapoff /dev/sda1").

Other useful commands for swap space:
"free -k" - Useful for seeing used swap space
"cat /proc/sys/vm/swappiness" - View the current swapiness parameter
"echo 90 > /proc/sys/vm/swappiness" - Change the swapiness parameter
