^(Wireless)连接USB 硬盘^{(USB HDD)}或闪存驱动器时，^{(Flash Drive)}无线鼠标和键盘停止响应

许多用户报告说他们的无线外围设备遇到了同样的问题。无线设备出现此问题的主要原因是USB 3.0和 2.0 端口的干扰问题，当两个端口位于笔记本电脑的同一侧时会发生这种情况。此干扰问题会导致对鼠标、键盘等无线设备的响应延迟。

要解决此问题，建议不要将USB 2.0和 3.0 设备连接到位于同一侧的端口。如果您的笔记本电脑两侧都有USB端口，请将您的无线外围设备和^(USB)闪存驱动器^{(Flash Drive)}连接到位于另一侧的USB端口。^(USB)

桌面^(Desktop)用户可以将设备连接到前后USB端口。

Wireless mouse and keyboard stop responding when a USB HDD or Flash Drive is connected

Many users have reported that they experienced the same problem with their wireless peripherals. The main cause of this problem with wireless devices is the interference issue with the USB 3.0 and 2.0 ports, which occurs when both the ports are located on the same side of the laptop. This interference issue causes a delayed response to wireless devices such as mice, keyboards, etc.

To solve this problem, it is suggested not to connect your USB 2.0 and 3.0 devices to the ports that are located on the same side. If your laptop has USB ports on both sides, connect your wireless peripherals and Flash Drive to the USB ports located on the opposite side.

Desktop users can connect the devices to front and back USB ports.

Hope this helps.
