	//----- SETUP USB -----
	//---------------------
	//The USB specifications require that USB peripheral devices must never source current onto the Vbus pin.  Additionally, USB peripherals should not source
	//current on D+ or D- when the host/hub is not actively powering the Vbus line.  When designing a self powered (as opposed to bus powered) USB peripheral
	//device, the firmware should make sure not to turn on the USB module and D+ or D- pull up resistor unless Vbus is actively powered.  Therefore, the
	//firmware needs some means to detect when Vbus is being powered by the host. A 5V tolerant I/O pin can be connected to Vbus (through a resistor), and
	//can be used to detect when Vbus is high (host actively powering), or low (host is shut down or otherwise not supplying power).  The USB firmware
	//can then periodically poll this I/O pin to know when it is okay to turn on the USB module/D+/D- pull up resistor.  When designing a purely bus powered
	//peripheral device, it is not possible to source current on D+ or D- when the host is not actively providing power on Vbus. Therefore, implementing this
	//bus sense feature is optional.  This firmware can be made to use this bus sense feature by making sure "USE_USB_BUS_SENSE_IO" has been defined in the
	//HardwareProfile.h file.    
    //	#if defined(USE_USB_BUS_SENSE_IO)
    //	tris_usb_bus_sense = INPUT_PIN; // See HardwareProfile.h
    //	#endif
    
	//If the host PC sends a GetStatus (device) request, the firmware must respond	and let the host know if the USB peripheral device is currently bus powered
	//or self powered.  See chapter 9 in the official USB specifications for details regarding this request.  If the peripheral device is capable of being both
	//self and bus powered, it should not return a hard coded value for this request.  Instead, firmware should check if it is currently self or bus powered, and
	//respond accordingly.  If the hardware has been configured like demonstrated on the PICDEM FS USB Demo Board, an I/O pin can be polled to determine the
	//currently selected power source.  On the PICDEM FS USB Demo Board, "RA2" is used for	this purpose.  If using this feature, make sure "USE_SELF_POWER_SENSE_IO"
	//has been defined in HardwareProfile.h, and that an appropriate I/O pin has been mapped to it in HardwareProfile.h.
    //	#if defined(USE_SELF_POWER_SENSE_IO)
    //	tris_self_power = INPUT_PIN;	// See HardwareProfile.h
    //	#endif
    
    
    //Enable the USB port now - we will check to see if Vbus is  powered at the end of init and disable it if not.
    //USBDeviceInit();	//usb_device.c.  Initializes USB module SFRs and firmware variables to known states.
