14 General Description:
15 This file is an example configuration (with inline documentation) for the USB
16 driver. It configures V-USB for USB D+ connected to Port D bit 2 (which is
17 also hardware interrupt 0 on many devices) and USB D- to Port D bit 4. You may
18 wire the lines to any other port, as long as D+ is also wired to INT0 (or any
19 other hardware interrupt, as long as it is the highest level interrupt, see
20 section at the end of this file).

37 * "Optional MCU Description" below, or you can connect D- to the interrupt, as
38 * it is required if you use the USB_COUNT_SOF feature. If you use D- for the
