【标题描述】安装openEuler 20.03或者22.03，打开KVM移动鼠标（或者不打开KVM，接上显示器和鼠标，在界面内移动鼠标），会一直打印USB驱动重连信息
【环境信息】
硬件信息：
1） 请使用VE或者Pro主板，VD主板无此现象
2） 怀疑为 内核和VE或Pro主板 兼容性问题
软件信息：
1） 20.03或22.03均有，为一个通用问题，非特定版本问题
【问题复现步骤】
1、选择一台 VE或者Pro主板的服务器，安装20.03或22.03 任意系统。
2、连接显示器，接上鼠标后在界面内移动鼠标。或者 打开KVM在界面内移动鼠标
3、窗口会打印USB设备重连信息
出现概率(必现)
【预期结果】
使用CentOS 7.6对比，移动鼠标不会出现USB设备重连
【实际结果】
此处仅放KVM信息截图，实际非KVM，使用真实鼠标也有此现象。
