2.2.3 Integrated Full-Speed USB Hub

The F5529 LaunchPad development kit requires only one USB connection to the host, thanks to an integrated USB hub (see Figure 11). The emulator and the target device share one USB cable and can be used simultaneously. This simplifies the development setup.

The eZ-FET lite emulator itself is a composite USB device, which means that it contains two USB interfaces:

  • A CDC interface (virtual COM port) for the emulation function
  • A CDC interface (virtual COM port) for the application UART

(For an explanation of USB interfaces, see the discussion in Step 2 of Section 1.3)

These interfaces can be found on the host PC. As an example, Device Manager can be used for this purpose on a Windows PC. (See Section 3.7 for instructions on starting Device Manager.) Look for the emulator interfaces under the "Ports" section (see Figure 12).

If you are using a Mac, see Section 2.2.2 for an explanation why these interfaces do not enumerate.

Although the MSP Debug Interface virtual COM port is accessible to any host application, do not try to interface with it; it is only intended for use with supported emulation tools, like CCS and IAR.

If you load a USB-equipped software application into the target MSP430F5529 device, then additional USB interfaces, defined by that software, will be enumerated on the host.

The TUSB2046 is a four-port hub, and two ports are unused. The unused ports are properly terminated and inaccessible.
