Tool/software: Code Composer Studio
Hi,
I created one project likeUSB and I copied entire code from example usb_dev_bulk and copied into the USB project. When I am running this program it is giving so many errors.. Is their any new things to add in below code....

But I am getting below mentioned errors..
I need help...
Thanks & regards,
