I have a F28069 launchpad and I am just trying to run the out-of-the-box demo. The LEDs light up, JP7 has a jumper and JP6 does not, the TI XDS100 A/B channels show up in the USB controllers section of the Device Manager but there is no serial port listed for the launchpad within the Ports (COM & LPT) section of the Device Manager. When I initially plugged up the launchpad, it said it installed all of the drivers correctly. What am I doing incorrectly?
