如果您最近从早期版本的Windows升级到Windows 10，那么您可能会遇到USB 端口(USB Ports)无法在您的 PC 上工作的问题。似乎USB 端口(USB port)不再识别任何USB 设备(USB device)，并且USB 设备(USB device)将无法工作。您的USB 设备(USB device)都无法使用USB Mouse、Keyboard、Printer 或 Pendrive(Printer or Pendrive)，因此问题肯定与USB 端口(USB Ports)有关，而不是设备本身。不仅如此，这个问题还与您系统拥有的所有USB 端口(USB Ports)有关，如果您问我，这将非常令人沮丧。
无论如何，用户已经尝试并测试了不同的工作解决方案来修复 USB 端口(Fix USB Ports)在Windows 10中不起作用的问题。但在此之前，让我们讨论一下导致USB(USB)端口不工作的一些原因：
- 电源问题
- 故障设备
- 电源管理设置
- 过时或损坏的 USB 驱动程序
- USB 端口损坏
现在您知道了各种原因，我们可以继续修复或解决这些问题。这些是经过试验和测试的方法，似乎适用于多个用户。尽管如此，由于不同的用户具有不同的配置和环境(configuration and environment)，因此无法保证对其他人有效的方法也适用于您。因此，不要浪费任何时间，让我们(time let)看看如何使用下面列出的故障排除指南(troubleshooting guide)实际解决此问题。

2.搜索疑难解答并单击(Search Troubleshoot and click)疑难解答(Troubleshooting.)。
3. 接下来，单击左窗格中的查看全部(View all)。
4. 单击并运行硬件和设备疑难解答。( Troubleshooter for Hardware and Device.)
5.上述疑难解答(Troubleshooter)可能能够修复在 Windows 10 中无法正常工作的 USB 端口。(Fix USB Ports Not Working in Windows 10.)
方法二：检查设备本身是否有问题(Method 2: Check if the device itself is faulty)
现在，您尝试使用的设备可能有故障，因此Windows无法识别它。要验证情况并非如此，请将您的USB 设备(USB device)插入另一台正常工作的 PC 并查看它是否正常工作。因此，如果设备在另一台 PC 上工作，您可以确定问题与 USB 端口有关(problem is related to USB Ports)，我们可以继续下一个方法。
方法3：检查您的笔记本电脑电源(Method 3: Check your laptops Power Supply)
如果由于某种原因您的笔记本电脑无法向USB 端口(USB Ports)供电，那么USB 端口(USB Ports)可能根本无法工作。要解决笔记本电脑电源(power supply)问题，您需要完全关闭系统。然后拔下电源线(power supply cable)，然后从笔记本电脑中取出电池。现在按住电源按钮(power button)15-20 秒，然后再次插入电池并连接电源(power supply)。打开系统电源并检查您是否能够修复(Fix USB Ports)Windows 10中的USB 端口不工作问题(Issue)。
方法 4：禁用选择性挂起功能(Method 4: Disable the Selective Suspend feature)
默认情况下， Windows(Windows)会切换您的USB控制器以节省电量（通常在设备未使用时），一旦需要设备，Windows会再次打开设备。但有时可能由于某些损坏的设置Windows无法打开设备，因此建议从(device and hence)USB控制器中删除省电模式。
1. 按 Windows 键 + R 然后输入devmgmt.msc并按Enter打开设备管理器(Device Manager)。

USB Ports Not Working in Windows 10 [SOLVED]
If уou recentlу upgraded from an earlier vеrsion of Windows to Windows 10, then you might be facing this issue where USB Ports are not working оn your PC. It seems the USB port no longer recognіzes any USB device and the USB device will not work. None of your USB devices will work it USB Mouse, Keyboard, Printer or Pendrivе, so the issue is definitely related to USΒ Ports rathеr than the device itself. And not only thіs but the issue will be related to all the USB Ports your system has which is quite frustrating if you ask me.
Anyway, the user has tried and tested different working solution to Fix USB Ports Not Working in Windows 10 issue. But before that, let us discuss what are some causes because of which the USB Ports are not working:
- Power Supply issues
- Faulty Device
- Power Management settings
- Outdated or corrupted USB drivers
- Damaged USB Ports
Now that you know the various causes, we can continue to fix or workaround for these problems. These are tried & tested methods which seem to work for several users. Still, there is no guarantee that what worked for others will also work for you as the different users have different configuration and environment. So without wasting any time let’s see how to actually fix this issue with the below-listed troubleshooting guide.
USB Ports Not Working in Windows 10 [SOLVED]
Make sure to create a restore point just in case something goes wrong.
Method 1: Run Hardware and Device Troubleshooter
1. Press Windows Key + X and click on Control Panel.
2. Search Troubleshoot and click on Troubleshooting.
3. Next, click on View all in the left pane.
4. Click and run the Troubleshooter for Hardware and Device.
5. The above Troubleshooter may be able to Fix USB Ports Not Working in Windows 10.
Method 2: Check if the device itself is faulty
Now it’s possible that the device you’re trying to use is faulty and hence it’s not recognizable by Windows. To verify that is not the case, plug your USB device in another working PC and see if it’s working. So if the device is working on another PC, you can be sure that the problem is related to USB Ports and we can continue with the next method.
Method 3: Check your laptops Power Supply
If for some reason your laptop fails to deliver power to USB Ports, then it’s possible that the USB Ports might not work at all. To fix the issue with the laptop power supply, you need to shut down your system completely. Then remove the power supply cable and then remove the battery from your laptop. Now hold the power button for 15-20 seconds and then again insert the battery and connect the power supply. Power ON your system and check if you’re able to Fix USB Ports Not Working Issue in Windows 10.
Method 4: Disable the Selective Suspend feature
Windows by default switch your USB controllers to save power (typically when the device is not in use) and once the device is needed, Windows again turns ON the device. But sometimes it’s possible because of some corrupt settings Windows cannot turn ON the device and hence it’s advisable to remove power saving mode from USB controllers.
1. Press Windows Key + R then type devmgmt.msc and hit Enter to open Device Manager.
2. Expand Universal Serial Bus controllers in the Device Manager.
3. Right-click on USB Root Hub and select Properties.
4. Now switch to Power Management tab and uncheck “Allow the computer to turn off this device to save power.”
5. Click Apply, followed by OK.
6. Repeat steps 3-5 for each USB Root Hub device in the above list.
7. Reboot your PC to save changes.
Method 5: Registry Fix
If the above settings are greyed out, or Power Management tab is missing, you can change the above setting via Registry Editor. If you have already followed the above step, then no need to continue, jump to the next method.
1. Press Windows Key + R then type regedit and hit Enter.
2. Navigate to the following registry key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\USB
3. Find DisableSelectiveSuspend in the right window pane, if it’s not present then right-click in an empty area and select New > DWORD (32-bit) value.
4. Name the above key as DisableSelectiveSuspend and then double click on it to change its value.
5. In the Value data field, type 1 to disable the Selective Suspend feature and then click OK.
6. Reboot your PC to save changes, and this should Fix USB Ports Not Working issue but if not, then continue with the next method.
Method 6: Disable and Re-enable the USB controller
1. Press Windows Key + R then type devmgmt.msc and hit Enter to open Device Manager.
2. Expand Universal Serial Bus controllers in the Device Manager.
3. Now right-click on the first USB controller and then click on Uninstall.
4. Repeat the above step for each of the USB controller present under Universal Serial Bus controllers.
5. Reboot your PC to save changes. And after the restart Windows will automatically reinstall all the USB controllers that you uninstalled.
6. Check the USB device to see whether it is working or not.
Method 7: Update Drivers for all of your USB Controllers
1. Press Windows Key + R then type devmgmt.msc and hit Enter to open Device Manager.
2. Expand Universal Serial Bus controllers in the Device Manager.
3. Now right-click on the first USB controller and then click Update Driver Software.
4. Select Search automatically for updated driver software and click Next.
5. Repeat the above step for each of the USB controller present under Universal Serial Bus controllers.
6. Reboot your PC to save changes.
Updating drivers seems to Fix USB Ports Not a Working issue in most cases, but if you’re still stuck then it might be possible that your PC’s USB Port might be damaged, continue to next method to know more about it.
Method 8: USB Port might be damaged
If none of the above methods seems to fix your problem, then the chances are that your USB ports might be damaged. You need to take your laptop to a PC Repair shop and ask them to check your USB Ports. If they are damaged, then the repairer should replace the USB Ports available for quite a low price.
