Can not find driver for MCU VIRTUAL COM DEMO

No COM port appeared after connecting the TWR-POS-K81 via USB to a Windows 7 (64-bit) PC! And instead of "MSD_CDC_device" (as described in the Quick Start Guide) showing in Other Devices in the Device Manager, "MCU Virtual Com Demo" appeared instead.


When I right click on the MCU VIRTUAL COM DEMO device, select "Update Driver Software ...", select "Browse my computer for driver software ...", then input "...\boards\twrk81f150m\usb_examples\usb_device_cdc_vcom\inf" as the folder to search (as suggested in some NXP Community post), I get the error "Windows was unable to install your MCU VIRTUAL COM DEMO Windows could not find driver software for your device ...".


Where is the driver for MCU VIRTUAL COM DEMO for the TWR-POS-K81?
