On systems that use udev, there is a virtual file system mounted on /dev with all the device nodes. Udev takes care of creating the device nodes found there. Because it is a virtual file system, it is created every time the system boots, so any changes you make are lost when you reboot. So you need to create a udev rule to create the device node for you when you plug in your USB device. The /sys file system is another virtual file system that contains information about the system hardware. The udev documentation contains information about tools to get information from it to help you in writing your own udev rules. Note: If you have the /sys directory tree, it is probably a safe assumption that you are using udev.
