You can still use a single cable for UART communication with PC and powering KIT-059, if used pins 12_6 and 12_7 for RX and TX, which are hard-wired to USB-UART converter located in KitProg. Once KIT-059 is programmed, you will find additional COM port in Device Manager.
To check USBUART issue, please post project bundle here: 1. Build->Clean. 2. File->Create Archive bundle->minimal. 3. Delete Generated_source folder inside archive to save space.
Thanks for the input.... As it turns out - was as simple as a bad cable.... Turns out I was using a USB-Micro cable that only provided power, and no data lines.. Lesson learned.
Thanks for your input anyways!
