Avocent Cyclades TS100 USB Audio Interface device. It worked the last time I tried it, but I cannot make any guarantees as to specifics. It was pulled from an old Payless Shoe Store location that I dismantled for the new store and was allowed to keep any electronics I found. This and the other listing on my page for networking cables are from this jobsite. They're all in great condition for electronics that weren't cared for at all, and while dusty in some places they appear almost as if new.
