鼠標被識別但無法使用時，可能是傳感器髒污、按鈕故障、驅(qū)動問題或連接異常所致。首先清潔傳感器並檢查物理損壞；其次通過設(shè)備管理器重新安裝或更新驅(qū)動程序；再嘗試更換USB端口、電池或使用藍牙重連；最後調(diào)整鼠標設(shè)置或進入安全模式排查第三方軟件干擾，多數(shù)情況下可解決通信小故障。

If your computer recognizes the mouse but it still doesn't work, it can be frustrating. The fact that it's detected means it's connected properly or at least partially functional, but something else is causing the issue — and it could be software-related, driver-related, or even a hardware quirk.

Here are some common causes and fixes you can try without needing advanced tools or skills.

Check for Physical Issues First

Even if the mouse is recognized, there might be physical problems preventing it from working correctly. This includes:

• Dirty or blocked sensors (especially on optical mice)
• Faulty buttons or scroll wheel that aren't registering clicks
• Damaged cable or USB port (if wired) or dead batteries (if wireless)

Try this:

• Clean the bottom sensor gently with a soft cloth.
• Swap batteries or try a different USB port.
• If possible, test the mouse on another computer to rule out hardware failure.

Sometimes the mouse works just fine elsewhere, which means the problem is with your system, not the device itself.

Reinstall or Update Mouse Drivers

A common reason for detection without functionality is outdated or corrupted drivers. Windows usually handles this automatically, but sometimes it needs a nudge.

Steps to try:

• Press Win X and choose Device Manager
• Expand Mice and other pointing devices
• Right-click your mouse and select Uninstall device
• Restart your PC — Windows should reinstall the drivers automatically

You can also go to the manufacturer's website (like Logitech or Razer) and download the latest official drivers if generic ones don't work.

Try Different Connection Methods

Some connection issues are subtle. For example, Bluetooth may show a mouse as "connected" but not actually active. Or a receiver might be having interference.

Things to test:

• If using a USB receiver, plug it into a different USB port
• If using Bluetooth, disconnect and reconnect the mouse
• Try a different USB cable or adapter (for wired or dongle-based setups)

Also, if you're using a USB hub, especially one not powered, try plugging directly into the laptop or desktop.

Adjust Mouse Settings or Test in Safe Mode

Windows has several settings that control how a mouse behaves — including pointer speed, button configuration, and touchpad overrides.

To check:

• Go to Settings > Devices > Mouse and make sure nothing unusual is selected
• Disable any third-party mouse software temporarily to see if it helps
• Boot into Safe Mode and test the mouse — if it works there, a background app or driver conflict is likely

If none of these steps help, it might be worth checking for Windows updates or resetting the mouse settings entirely.

Most of the time, one of these fixes will get things working again. It's usually not a major system failure — just a small hiccup in communication between the mouse and your computer.
