修改 hid.c 文件，此文件在 kernel/drivers/usb/gadget/legacy/目录下，增加以下内容：

增加 hidg_func_descriptor 结构变量

static struct hidg_func_descriptor my_hid_data = {
.subclass = 0, /* No subclass */
.protocol = 2, /* Keyboard */
//.report_length = 6,
.report_length = 62,//14,//13,//6,
// .report_desc_length = 74,
.report_desc_length = 489,//515,//176
.report_desc = {
