beyond is available with a USB connector hanging off the side.
Linux support for devices has traditionally been a slightly crufty area.
Devices that are plugged in usually require several manual steps before the
OS recognizes them, and they are accessible to the user. But in the last two
years the ease of hardware handling has improved dramatically. One of the
major projects to work on this problem is Project Utopia. This collection of
developers has worked to create a software stack that enables you to plug a
device into your USB port and have it just work. This stack includes the fol-
