General Description:
This file contains parts of the USB driver which can be configured and can or
must be adapted to your hardware.

Please note that the usbdrv contains a usbconfig-prototype.h file now. We
recommend that you use that file as a template because it will always list
the newest features and options.
*/

/* ---------------------------- Hardware Config ---------------------------- */

#define USB_CFG_IOPORTNAME      C
/* 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.
*/

/* This is the bit number in USB_CFG_IOPORT where the USB D- line is connected.
* This may be any bit in the port.
*/

/* 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!
*/

/* ----------------------- Optional Hardware Config ------------------------ */

/* #define USB_CFG_PULLUP_IOPORTNAME   D */
/* If you connect the 1.5k pullup resistor from D- to a port pin instead of
* V+, you can connect and disconnect the device from firmware by calling
* the macros usbDeviceConnect() and usbDeviceDisconnect() (see usbdrv.h).
* This constant defines the port on which the pullup resistor is connected.
*/

/* Define this to 1 if you also want to implement the ENDPOINT_HALT feature

* bloats the code considerably.

/* Set this to 1 if you need to send control replies which are generated
* "on the fly" when usbFunctionRead() is called. If you only want to send
* data from a static buffer, set it to 0 and return the data from
* usbFunctionSetup(). This saves a couple of bytes.
*/

* of the macros usbDisableAllRequests() and usbEnableAllRequests() in

/* ------------------- Fine Control over USB Descriptors ------------------- */
/* If you don't want to use the driver's default USB descriptors, you can
* provide our own. These can be provided as (1) fixed length static data in
* 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().
*   + 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)
