MSP430I2041: Canot connect from board to energy measurement design center

Part Number: MSP430I2041
Other Parts Discussed in Thread: MSP-EXP430F5529LP, UNIFLASH, EVM430-I2040S

Tool/software:

Hello everyone,
I design an application about energy metering, using MSP430i2041 as controller.
I use energy measurement design center to configuration and create project base on CCS, upload program to controller is ok.
I can not connect to controller via energy metering design center, using MSP-EXP430F5529LP as HID device, no response from my device.
Pls help me to debug.
- I also upload the programm via CCS, or via Uniflash ->Upload ok.
- I have an IAR based program for EVM430-I2040S (program for reference but it can handle on my board), it can work (communication via uart with calibrator, upload program...)
