MCF51JM128 coldfire bootloader not working

I recreated a boot loader program from AN3748. System specs:

1) Window 7 64bit.

2) Code warrior 10.7

3) Target processor MCF51JM128.


Issues: The attached project is meant to act as a bootloader as well as user application.

1)   Built 1 forces firmware to execute user program and blink LED continuously on port D7 works well.

2)   Built 2 forces firmware to go into boot-loader mode. When in this mode, the board doesn't seem to be enumerating and I get driver installation error in windows.

Can someone please take a look at the code and suggest what where I might be going wrong?
