Query: Computer can not locate DDREADER-14

I gave this reader to my son as a Christmas gift and he tried it out on his father-in-law's system (which he built) and the system can not locate it. When he arrives back at his home, he will contact the mfg for software updates and install it on his system. If he gets it working, I will update this review with information on the fix. If it does not work, it is defective and we will return it for a replacement.
