//---------------------
//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
