15 General Description:
16 This file is an example configuration (with inline documentation) for the USB
17 driver. It configures V-USB for USB D+ connected to Port D bit 2 (which is
18 also hardware interrupt 0 on many devices) and USB D- to Port D bit 4. You may
19 wire the lines to any other port, as long as D+ is also wired to INT0 (or any
20 other hardware interrupt, as long as it is the highest level interrupt, see
21 section at the end of this file).
22 + To create your own usbconfig.h file, copy this file to your project's
23 + firmware source directory) and rename it to "usbconfig.h".
24 + Then edit it accordingly.

294 * information about this function.
295 * Descriptor handling is configured through the descriptor's properties. If
296 * no properties are defined or if they are 0, the default descriptor is used.
297 * Possible properties are:
298 * + USB_PROP_IS_DYNAMIC: The data for the descriptor should be fetched
299 * at runtime via usbFunctionDescriptor(). If the usbMsgPtr mechanism is
300 * used, the data is in FLASH by default. Add property USB_PROP_IS_RAM if

302 * + USB_PROP_IS_RAM: The data returned by usbFunctionDescriptor() or found
303 * in static memory is in RAM, not in flash memory.
304 * + USB_PROP_LENGTH(len): If the data is in static memory (RAM or flash),
305 * the driver must know the descriptor's length. The descriptor itself is
306 * found at the address of a well known identifier (see below).
307 * List of static descriptor names (must be declared PROGMEM if in flash):
308 * char usbDescriptorDevice[];
309 * char usbDescriptorConfiguration[];
310 * char usbDescriptorHidReport[];
311 * char usbDescriptorString0[];
312 * int usbDescriptorStringVendor[];

314 * int usbDescriptorStringSerialNumber[];
315 * Other descriptors can't be provided statically, they must be provided
316 * dynamically at runtime.

319 * #define USB_CFG_DESCR_PROPS_DEVICE (USB_PROP_IS_RAM | USB_PROP_LENGTH(18))
320 *
321 * The following descriptors are defined:
322 * USB_CFG_DESCR_PROPS_DEVICE
323 * USB_CFG_DESCR_PROPS_CONFIGURATION
324 * USB_CFG_DESCR_PROPS_STRINGS
325 * USB_CFG_DESCR_PROPS_STRING_0

331 * USB_CFG_DESCR_PROPS_UNKNOWN (for all descriptors not handled by the driver)
332 *
333 * Note about string descriptors: String descriptors are not just strings, they
334 * are Unicode strings prefixed with a 2 byte header. Example:
335 * int serialNumberDescriptor[] = {
