鼠标开机不亮，需要重新插拔恢复，罗技鼠标掉驱动开机不亮不通电等，终极原因与解决方案

USB 选择性挂起功能允许集线器驱动程序挂起单个端口，而不会影响集线器上其他端口的操作。选择性悬挂 USB 设备在便携式计算机中特别有用，因为它有助于节省电池电量。许多设备，如指纹读取器和其他类型的生物识别扫描仪，只是间歇性地需要电源。在设备不使用时挂起此类设备可降低总体功耗。更重要的是，任何未有选择地挂起的设备都可能阻止 USB 主控制器禁用其驻留在系统内存中的传输计划。主机控制器对调度程序的直接内存访问 （DMA） 传输可以防止系统的处理器进入更深的休眠状态。

方法一 通过设备管理器关闭（此方法最精准，但如果是网吧，主板型号过多，全都需要设置，不方便）：

对于 Microsoft Windows XP 的升级版本，已禁用选择性挂起。它适用于 Windows XP、Windows Vista 和更高版本的 Windows 的全新安装。    若要为给定根集线器及其子设备启用选择性挂起支持，请在设备管理器中选中 USB 根集线器的“电源管理”选项卡上的复选框。

方法二 通过驱动文件来关闭（一般鼠标会自动驱动，所以通过此方法不方便）：

或者，您可以通过在 USB 端口驱动程序的软件密钥下设置 HcDisableSelectiveSuspend 的值来启用或禁用选择性挂起。值为 1 将禁用选择性挂起。值为 0 将启用选择性挂起。

例如，Usbport.inf 中的以下行禁用 Hydra OHCI 控制器的选择性挂起：

[OHCI_NOSS.AddReg.NT]

HKR,,"HcDisableSelectiveSuspend",0x00010001,1

方法三 通过注册表关闭（最为方便，建议使用此方法）：
