I think you need to provide a LOT MORE INFORMATION for any possibility of an answer here perhaps. Above the question field in the place you ask the question in BOLD RED writing is a request for information.... please review that request and update your question.

Windows will recognize the AudioBox USB, but only as a record input device. You must install the device drivers to make it work correctly.
