This MAY help a bit - it describes a USB connected player based on the same chip as I think yours is, so the comments about built-in Windows USB drivers etc., should be relevant.

You may also likt to try Audacity software once you have the thing connected. I find it quite good. You need to instal the LAME MP3 encoder - they aren't allowed to distribute it "packaged" - but there are simple instructions on the Audacity website.
