i had the same problem with these adapters. the first one i bought was called an "easy go usb2.0 to ide adapter" no web site support at all. it actually worked the first time then quit. i went crazy looking for info on it but found nothing. i finally got another on ebay. i bought the whole aluminum case and just took the guts out. works flawlessly. had to extend the molex and wired up 5v from the computer ps it was like $40us i think.
