I love my Transformer but the extra short proprietary cable drives me crazy. I picked up a USB extension cable but it did not work. I was then reading that you MUST use a USB 3.0 cable to extend the OEM Transformer USB cable. I purchased the below from Amazon for 12 bucks. I just received it and it works great. Now I can extend my power cable an additional 6 feet.
OK, the color is ugly but since it is buried behind my desk you don't see it. I'm sure you can find a cheaper version on eBay but I wanted it right away and knew I could easily return it if it did not work.
