Hello all....I have been using the USB757 for almost 2 years and all of a sudden its not wanting to work right. It keeps disconnecting me and then it locks up. I was just wondering if it was the device or the computer I'm using it on. The computer I have is a dell e510. I have had this computer for about 4 years now. I'm just needing a little advice on what to do. Please and Thank-you.
