MSP430FR6047: connecting my EVM430FR-6047 to PC: "HID bridge connected-waiting for device"

Part Number: MSP430FR6047

Tool/software:

When connecting EVM430FR-6047 to PC and ultrasonic sensing design center (water mode), I get the following error: "HID bridge connected-waiting for device". what is the reason for this error?

I have already connected two ultrasound probes to J8; vertically as CH0 and 1. Of course the ground is also connected (Audiowell did not respond! so I got H2KMPYA1000600 USS probes from Digikey)! I have already flashed the "FR6047_USSSWLib_template_example" into the EVM board. During the flashing, LED D100 was blinking red, and during the debug it was solid red. Now the board has two green LEDs ON (solid); D101 and D201. However, when I am trying to "Connect" the "USS" GUI to the board, the GUI either freezes or give me the following message: "HID bridge connected-waiting for device". I read similar questions on the forum, and tried the solutions, but it did not help. How can I fix the error?
