Query: USB to Serial

I bought this cable for a seldom-used device and did not want to spend a lot of money. Now I wish I had. There are no instructions and no phone number or Web site to contact for help. After trying to load the driver software on both computers nothing happened. I tried uninstalling and loading several times, but this cable failed each time. I am extremely disappointed in this product. When I ordered it there were no reviews. Now I will purchase a cable that has been reviewed by other customers and highly recommend against anyone buying this one.
