Nisam radio sa USB-om ali uz CCS C si dobio prilican broj primera a evo vezano za USB:

ex_usb_hid.c - A simple HID device
ex_usb_mouse.c - A HID Mouse, when connected to your PC the mouse cursor will go in circles.
ex_usb_kbmouse.c - An example of how to create a USB device with multiple interfaces by creating
a keyboard and mouse in one device.
ex_usb_kbmouse2.c - An example of how to use multiple HID report Ids to transmit more than one
type of HID packet, as demonstrated by a keyboard and mouse on one device.
ex_usb_scope.c - A vendor-specific class using bulk transfers is demonstrated.
ex_usb_serial.c - The CDC virtual RS232 library is demonstrated with this RS232 < - > USB example.
ex_usb_serial2.c - Another CDC virtual RS232 library example, this time a port of the ex_intee.c
example to use USB instead of RS232.
