AVRUSB 无线（红外）多媒体键盘的实现（已完成）键盘+鼠标+多媒体---附源码
下面为键盘的电路图，仅为一个遥控器！
M48接收器的电路就用USBASP的电路即可，但在PD3口加一个红外一体接收头！
遥控器大家可以自己做一个即可，NEC格式，客户码0x00ff，data从00--ff，自己定义，同时可以修改的可以自己改！以适应自己的遥控。
这是我鼠标与键盘都OK的，键盘带modifierkey的描述：
static const char hidReportDescriptor0[] PROGMEM = {
/* partial keyboard */
0x05, 0x01, // Usage Page (Generic Desktop),
0x09, 0x06, //Usage (Keyboard),
0xA1, 0x01, // Collection (Application),
0x85, 0x01, // Report Id (1) //报告类型为1
0x05, 0x07, // USAGE_PAGE (Keyboard)
0x19, 0xe0, // USAGE_MINIMUM (Keyboard LeftControl)
0x29, 0xe7, // USAGE_MAXIMUM (Keyboard Right GUI)

0x25, 0x01, // LOGICAL_MAXIMUM (1)

0x19, 0x00, // Usage Minimum (0),
0x29, 0xff, // Usage Maximum (101),
0x81, 0x00, // Input (Data, Array), ;Key arrays (4 bytes)
0xC0, //

0x05, 0x01, /* Usage Page (Generic Desktop), */
0x09, 0x02, /* Usage (Mouse), */
0xA1, 0x01, /* Collection (Application), */
0x09, 0x01, /* Usage (Pointer), */
0xA1, 0x00, /* Collection (Physical), */
0x05, 0x09, /* Usage Page (Buttons), */
0x19, 0x01, /* Usage Minimum (01), */
0x29, 0x03, /* Usage Maximun (03), */
0x15, 0x00, /* Logical Minimum (0), */
0x25, 0x01, /* Logical Maximum (1), */
0x85, 0x02, /* Report Id (2) */
0x95, 0x03, /* Report Count (3), */
0x75, 0x01, /* Report Size (1), */
0x81, 0x02, /* Input (Data, Variable, Absolute), ;3 button bits */
0x95, 0x01, /* Report Count (1), */
0x75, 0x05, /* Report Size (5), */
0x81, 0x01, /* Input (Constant), ;5 bit padding */
0x05, 0x01, /* Usage Page (Generic Desktop), */
0x09, 0x30, /* Usage (X), */
0x09, 0x31, /* Usage (Y), */
0x15, 0x81, /* Logical Minimum (-127), */
0x25, 0x7F, /* Logical Maximum (127), */
0x75, 0x08, /* Report Size (8), */
0x95, 0x02, /* Report Count (2), */
0x81, 0x06, /* Input (Data, Variable, Relative), ;2 position bytes (X Y) */
0xC0, /* End Collection, */
0xC0, /* End Collection */
};
这个键盘带有鼠标功能。然后在这个基础上修改，我先仅仅实现多媒体按键，看了 computer00的代码。
static const char hidReportDescriptor0[] PROGMEM = {
/* partial keyboard */
0x05, 0x0c, // USAGE_PAGE (Consumer Page)
0x09, 0x01, // USAGE (Consumer Control)
0xa1, 0x01, // COLLECTION (Application)
0x09, 0xea, // USAGE (Volume Decrement)
0x09, 0xe9, // USAGE (Volume Increment)
0x09, 0xe2, // USAGE (Mute)
0x09, 0xcd, // USAGE (Play/Pause)
0x15, 0x00, // LOGICAL_MINIMUM (0)
0x25, 0x01, // LOGICAL_MAXIMUM (1)
0x95, 0x07, // REPORT_COUNT (4)
0x75, 0x01, // REPORT_SIZE (1)
0x81, 0x02, // INPUT (Data,Var,Abs)
0x75, 0x01, // REPORT_SIZE (1)
0x95, 0x01, // REPORT_COUNT (4)
0x81, 0x03, // INPUT (Cnst,Var,Abs)
0xc0 // END_COLLECTION
};
其他地方也适当修改，没有问题，这样修改后能出现 HID 用户控制设备。这就是多媒体键盘会出现的。

/* partial keyboard */

0x09, 0x06, //Usage (Keyboard),

上面是最好的描述符，已经完成多媒体键盘以及鼠标，键盘的实现，虽然没有人回答我，帮我解决问题，但还是在多次的努力，及多次电脑的重启下完成了。还是那句话，努力后一定有回报。
