Query: DOA...had to return.

This Sabrent media card reader and writer was dead out of the box. I tried on 4 different computers and also tried the Sabrent website to see if there was an update or something for this unit. I also contacted them and were told it must be DOA and to return it where I got it. It seemed like a great product, however this one was a big let down so far.
