It configures V-USB for USB D+ connected to Port D bit 2 (which isalso hardware interrupt 0 on many devices) and USB D- to Port D bit 4. You maywire the lines to any other port, as long as D+ is also wired to INT0 (or anyother hardware interrupt, as long as it is the highest level interrupt, seesection at the end of this file).*//* ---------------------------- Hardware Config ---------------------------- */#define USB_CFG_IOPORTNAME      D/* This is the port where the USB bus is connected. When you configure it to * "B", the registers PORTB, PINB and DDRB will be used. */#define USB_CFG_DMINUS_BIT      4/* This is the bit number in USB_CFG_IOPORT where the USB D- line is connected. * This may be any bit in the port. */#define USB_CFG_DPLUS_BIT       2/* This is the bit number in USB_CFG_IOPORT where the USB D+ line is connected. * This may be any bit in the port. Please note that D+ must also be connected * to interrupt pin INT0! [You can also use other interrupts, see section * "Optional MCU Description" below, or you can connect D- to the interrupt, as * it is required if you use the USB_COUNT_SOF feature. If you use D- for the * interrupt, the USB interrupt will also be triggered at Start-Of-Frame * markers every millisecond.] */#define USB_CFG_CLOCK_KHZ       (F_CPU/1000)/* Clock rate of the AVR in kHz.
