触摸屏的HID 报告中，
0x05, 0x0d,                      // USAGE_PAGE (Digitizers)
0x09, 0x54,                      // USAGE (Contact Count)
0x95, 0x01,                      // REPORT_COUNT (1)
0x75, 0x08,                      // REPORT_SIZE (8)
0x15, 0x00,                      // LOGICAL_MINIMUM (0)
0x25, 0x08,                      // LOGICAL_MAXIMUM (8)
0x81, 0x02,                      // INPUT (Data,Var,Abs)
0x09, 0x55,                      // USAGE(Contact Count Maximum)
0xb1, 0x02,                      // FEATURE (Data,Var,Abs)
该报告中的feature数据该如何操作？谢谢~！
