There are many example programs on USB and HID interface in CCS you can include and modify their functions to suit your program. Also you don't need driver for HID as PC has it in its operating system.
You can download a PC software tool for testing your connection from Microchip website. This program is intended for one of Microchip Kits but you can modify the microcontroller program to use it without its kit.
Or you can make your own PC program to test connection.
Finally, if HID has not enough speed for your use, you can use bulk transfer type.
