MSP430F5529: USB interface with msp430f5529

Hi Experts,

I was trying to achieve a USB interfaced project using MSP430F5529 using USB descriptor and CDC class

when i try to upload code into the board showing error unknown device like,

the steps i have taken to upload the code is,

1. Generated CDC files from USB Descriptor
2. Imported C1-LEDOn/Off project 
3. copy pasted the generated files from USB Descriptor including Inf file
4. Build happen 
5. I kept GND, 5V & 3V3 jumpers and removed remaining(i hope this is the way to do an USB Project)
6. connected the USB cable to the host computer
7. and clicked run

Ports Shown:

1. UART1 

2. Debug Interface

3. USB serial Device 

Working with the USB serial device port

Also i connected all jumpers and uploaded the code still LED not blinking (don't how to do it actually but eager to learn about it :-) )

and the error coming as mentioned in the above image 

Please help me, any suggestions will be greatly appreciated!

Best regards,
