Is there an external optical drive that will work with the surface pro 3? I bought a LG GP50NB40 from Amazon and it worked at first with one USB (installed office), but then when I tried to install the Sims 2, it kept ejecting itself. I eventually got an "overloaded USB port" message. I bought a USB Y cable (with a USB female end and 2 USB male ends) and tried plugging the drive into the female connector with one male end into the surface USB and the other male end into the USB port on the power supply. The drive booted up, but the surface didn't detect it. Obviously, this drive will not work with the surface and I'm getting ready to return it to Amazon. I don't use disks often, but for burning an occasional movie and installing software, I'd like to have one available. Does anyone have any suggestions for one that will work with the surface? Thanks!
