我移植了AVRCDC到LGT上。正常认出COM口。但是打开发送数据的时候,输出端并没有任何数据。这个让我觉得非常奇怪。
我移植后的代码是:

- /* ------------------- 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(). 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'
- * };
