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

| /* ------------------- Fine Control over USB Descriptors ------------------- */ |
| /* If you don't want to use the driver's default USB descriptors, you can |

| * flash memory, (2) fixed length static data in RAM or (3) dynamically at |
| * runtime in the function usbFunctionDescriptor(). See usbdrv.h for more |
| * information about this function. |
| * Descriptor handling is configured through the descriptor's properties. If |
| * no properties are defined or if they are 0, the default descriptor is used. |
| * Possible properties are: |
| * + USB_PROP_IS_DYNAMIC: The data for the descriptor should be fetched |
| * at runtime via usbFunctionDescriptor(). If the usbMsgPtr mechanism is |
| * used, the data is in FLASH by default. Add property USB_PROP_IS_RAM if |
| * you want RAM pointers. |
| * + USB_PROP_IS_RAM: The data returned by usbFunctionDescriptor() or found |
| * in static memory is in RAM, not in flash memory. |
| * + USB_PROP_LENGTH(len): If the data is in static memory (RAM or flash), |
| * the driver must know the descriptor's length. The descriptor itself is |
| * found at the address of a well known identifier (see below). |
| * List of static descriptor names (must be declared PROGMEM if in flash): |
| * char usbDescriptorDevice[]; |
| * char usbDescriptorConfiguration[]; |
| * char usbDescriptorHidReport[]; |
| * char usbDescriptorString0[]; |
| * int usbDescriptorStringVendor[]; |
| * int usbDescriptorStringDevice[]; |
| * int usbDescriptorStringSerialNumber[]; |
| * Other descriptors can't be provided statically, they must be provided |
| * dynamically at runtime. |
| * |
| * Descriptor properties are or-ed or added together, e.g.: |
| * #define USB_CFG_DESCR_PROPS_DEVICE (USB_PROP_IS_RAM | USB_PROP_LENGTH(18)) |
| * |
| * The following descriptors are defined: |
| * USB_CFG_DESCR_PROPS_DEVICE |
| * USB_CFG_DESCR_PROPS_CONFIGURATION |
| * USB_CFG_DESCR_PROPS_STRINGS |
| * USB_CFG_DESCR_PROPS_STRING_0 |
| * USB_CFG_DESCR_PROPS_STRING_VENDOR |
| * USB_CFG_DESCR_PROPS_STRING_PRODUCT |
| * USB_CFG_DESCR_PROPS_STRING_SERIAL_NUMBER |
| * USB_CFG_DESCR_PROPS_HID |
| * USB_CFG_DESCR_PROPS_HID_REPORT |
| * USB_CFG_DESCR_PROPS_UNKNOWN (for all descriptors not handled by the driver) |
| * |
| * Note about string descriptors: String descriptors are not just strings, they |
| * are Unicode strings prefixed with a 2 byte header. Example: |
| * int serialNumberDescriptor[] = { |
| * USB_STRING_DESCRIPTOR_HEADER(6), |
| * 'S', 'e', 'r', 'i', 'a', 'l' |
| * }; |
