MSP430F5529 USB communication drivers refuse to install correctly
From your comment, I got what your problem. Your launchpad only have 1 USB connector compare to a Launchpad like  this. When you are running a debug session, the bus is converted to UART to talk with the FTDI chip and the programming MCU therefore you cannot run a USB application at the same time with the example TI give you. When you just connect your launchpad, Window do a enumaration of your board and therefore the LP is detected as USB device and the application work fine. So in fact the example are working. If you want to debug &amp; use the usb bus at the same time, it will require a lot of work, because you will have to develop code that share the bus alternatively between code composer and the USB application.
