通信传输

基础传输层，表示一个抽象的通信后端

打开设备，使用设备路径打开

int open(char *path);

unsigned char *getInputReport(int lenth);

int read(unsigned char *data,unsigned long lenth);

int write(unsigned char *data,unsigned long lenth);

void freeEnumerate(hid_device_info *devs);

hid_device_info *enumerate(int vid, int pid);

int setBrightness(int percent);

int setBackgroundImg(unsigned char *buffer);

int setKeyImg(std::string path,int key);

int keyClear(int i);

int keyAllClear();

int wakeScreen();

int refresh();

int disconnected();

void close();
