The 'USB' tag is to be used when you are looking for a recommendation for a program that involves a USB flash drive (or 'memory stick'). If you are looking for a program that runs on a USB device (ie. portable), then use the '[portable][1]' tag.

For more information on USB flash drives, see this [Wikipedia][2] article.
