USBX HID 设备问题现象：以鼠标举例, 假设第一个插入的鼠标为1号鼠标， 第二个插入的为2号鼠标，2个鼠标都插入后，将2号鼠标拔出，此时1号鼠标也将不能使用。
更严重的影响：发生内存踩踏2号鼠标被拔出后，它所使用的内存将被释放，此时1号鼠标动作虽然使用api获取的属性值(x/y坐标、按键值、滚轮值)没有改变，当实际原因是1号鼠标的属性值被更新到2号鼠标原先属性值所在的内存中去了。1号鼠标仍在操作原本已经被释放的2号鼠标的内存。
LOG分析：鼠标插入:从LOG上可以看出插入一号鼠标后 一号鼠标的 mouse_instance = 0x2116D830 接着插入2号鼠标 mouse_instance = 0x21174140 从下面这2条LOG可以看出 他们所属的hid客户端是同一个，也就是调用ux_host_class_hid_client_register(_ux_system_host_class_hid_client_mouse_name, ux_host_class_hid_mouse_entry)注册鼠标客户端时malloc的一片内存。
鼠标枚举LOG _ux_host_class_hid_mouse_activate源码:从这个.c的源码中也能看出，这里 hid_client -> ux_host_class_hid_client_local_instance = (VOID *) mouse_instance;的操作会覆盖原本的这个值, 即使这个鼠标枚举失败了 hid_client -> ux_host_class_hid_client_local_instance也没有恢复操作，1号原本可以使用的对象就直接丢失了。(这里就不分析这个情况了，看代码就能理解了) /* Get some memory for both the HID class instance of this client
and for the callback. */
mouse_instance = (UX_HOST_CLASS_HID_MOUSE *) _ux_utility_memory_allocate(UX_NO_ALIGN, UX_REGULAR_MEMORY, sizeof(UX_HOST_CLASS_HID_MOUSE));
