For those who are having a problem, ask customer service to send you the drivers and if they refuse, ask to speak to someone like a supervisor and get their name. Then ask them if they can explain to you why this problem exists.
The two units I had here all crapped out on me after a week, one I could not get to work even with a fresh windows X install. I spent sometime on the phone with these idiots and told them simply that it is defective product and demanded that they send me the drivers, which I am still waiting for them. My client who I was reviewing them for, talked to T/A management to complain about the poor quality of the product and how this makes T/A look like idiots, one reason why it isn't on the shelves at some T/As.
