• On Windows 10, a device driver is an essential piece of code, which allows the system to interact with a specific hardware (such as graphics card, storage driver, network adapter, Bluetooth, etc.

Solutions:

Solution 1: Plug into USB 2.0 Port to try

If you connect a USB device to the USB port, but the USB port stops responding, on that occasion, your USB device will not be recognized by Windows 10. You can try to plug it into another USB port to have a try. Especially, if there are USB 2.0 ports, try to plug it into the USB 2.0 port. Some USB devices may not work in USB 3.0 port, but it will work in USB 2.0 port.

The one that communicates with our layout NCE power module through the serial port has stopped communicating and Windows Vista device manager reports the PCI serial port driver is missing and also the PCI simple communications controller and PCI bus controller drivers.

The USB 3.0 Port is blue and the USB 2.0 port is black or white. Just check whether you have plugged into the wrong port, thus leading to USB port not working on Windows 10. But if you find that your USB ports are not responding in another USB port or on the USB port on another PC, you can consider replacing a new one as it may be a broken USB port.

Solution 2: Check the Laptop Power Supply

If you are using a laptop, and your USB ports had no response when you plug a USB device to it, maybe it is the power problem. The computer may have a problem with the power supply for USB devices and USB ports. So resetting it will be a choice.

1. Unplug the laptop supply and charger plug from your computer.

2. Wait for several minutes, for some of the manufacturer laptops such as HP, maybe need 15 minutes.

3. Then plug the laptop supply and charger again.

4. Restart the computer.

5. Connect the USB devices to the USB ports to have a try.

After inspecting the hardware condition of your USB port and computer, but you still noticed Windows 10 USB ports not working, keep going on for more ways.

Solution 3: Scan for Hardware Changes

Windows will detect the new hardware after rebooting the computer or by the scan for hardware changes function in device manager. So you can plug the USB device and reboot the computer again to check if the USB port works or not. Of course, if you have no idea to reboot, you can scan for hardware changes.

1. Enter the device manager.

2. Click the scan for hardware changes icon in the view drop-down option.

This will help scan for all the added and removed hardware.

If the system detects out that one device is added to the computer when you connected a USB device to the USB port, it will add it to device manager list and windows will install the driver for the device automatically. If the driver cannot be installed correctly, it will show you a yellow exclamation.

Of course, if one device is removed from the computer, for instance, you plugged out a USB device, it will also be deleted by the device manager.

3. If the scan for hardware changes cannot help, try to restart the computer again to check if the computer can identify the USB devices.

Now maybe after scanning for hardware changes, your USB ports can work properly. If the problem can’t be fixed, try the following solutions.

Solution 4: Change Power Management Settings

Drivers Launch Port Devices Android

Sometimes because of the power saving settings for the USB devices, the USB devices will be unresponsive. So you can disable this setting in the USB root hub.

1. Open device manager and expand Universal Serial Bus Controllers.

2. Find the USB Root hub or USB Root Hub (3.0), right-click it and choose Properties.

3. Locate Power Management tab in the USB Root HUB Properties window, and uncheck the option: Allow the computer to turn off this device to save power.

This will allow USB devices to use the system power anytime. Possibly, the USB port doesn’t work due to the power saver settings.

4. Find all the USB Root HUB and uncheck this option.

After that, connect the USB devices to check if it can work or not.

And if you can do nothing about this option because it is grayed out or missing, here is the solution: how to fix allow the computer to turn off this device to save power grayed out problem.

Solution 5: Uninstall the USB Controller Drivers

The USB controller will be the reason to disable USB ports response. So you can disable the USB controller and enable it again.

1. Enter the device manager and expand Universal Serial Bus Controllers.

2. Find the USB controller, right-click it and choose Uninstall device, this will uninstall the USB controller.

3. Find other USB controllers to uninstall them one by one.

4. Restart the computer after all the USB controllers uninstalled. After Windows 10 restart, the system will automatically scan for hardware changes and reinstall all the USB controllers again.

Solution 6: Reinstall the USB Driver

The USB ports cannot work properly may be caused by the USB devices driver or the related drivers such as the motherboard and chipset drivers. So updating drivers can help to solve it. For updating the drivers, you can enter the device manager to update it or download the drivers from the device manufacturer’s website and install it manually.

Of course, if you have a problem with updating it by yourself, you can use Driver Booster to help you. It can fix the driver issues easily and fast as Driver Booster will scan, download, and install the USB driver or other device drivers automatically from its 3-plus million driver database.

1. Download Driver Booster on Windows 10.

2. After installing and running it, hit Scan to get it started to search for outdated, missing, and faulty drivers.

Perhaps the USB driver display in the to-be-updated list. That may be the reason why computer USB ports are not working on Windows 10.

3. Find out Universal Serial Bus controllers and then click Update.

4. Here if you noticed many other device drivers, such as that of motherboard or graphics card, you may as well choose to Update Now to update all the device drivers for Windows 10.

As you can see, Driver Booster can help scan all the devices, including the plugged-in USB devices and their ports, chipset devices, motherboard and so on. And then recommend the latest drivers to you. After all the USB device drivers are updated, you can connect it to the USB port to check if the USB devices can work with the USB ports.

Solution 7: Disable Selective Suspend Setting

In the last place, as per USB port not working on Windows 10, from users’ reports and research, it does exist a relevant option – Selective Suspend feature in the power saver settings. This Selective suspend feature is used to suspend USB devices so as to save power, sometimes, it will even turn off the USB devices.

You can manage to turn off this feature to fix USB port error on Windows 10.

1. Go to Start > Settings > System.

2. Under Power & Sleep, choose Additional power settings.

3. Then try to Change power plan.

4. In Edit Plan Settings window, hit Change advanced power settings.

5. In Power Options, locate and expand USB settings and then open USB selective suspend settings to Disable

The time you click Apply and OK to save the changes, Windows 10 will also be disabled from disabling your USB devices.

You can find now USB ports are working on Windows 10 as your USB mouse and keyboard will all run well.

Wish these solutions can make your USB ports work normally and the USB devices be recognized by Windows 10.

The Ethernet switch device driver model (switchdev) is an in-kernel drivermodel for switch devices which offload the forwarding (data) plane from thekernel.

The “offload” flag is set in case at least one device offloads the FIB entry.

Nexthop Resolution¶

The FIB entry’s nexthop list contains the nexthop tuple (gateway, dev), but forthe switch device to forward the packet with the correct dst mac address, thenexthop gateways must be resolved to the neighbor’s mac address. Neighbor macaddress discovery comes via the ARP (or ND) process and is available via thearp_tbl neighbor table. To resolve the routes nexthop gateways, the drivershould trigger the kernel’s neighbor resolution process. See the rockerdriver’s rocker_port_ipv4_resolve() for an example.

The driver can monitor for updates to arp_tbl using the netevent notifierNETEVENT_NEIGH_UPDATE. The device can be programmed with resolved nexthopsfor the routes as arp_tbl updates. The driver implements ndo_neigh_destroyto know when arp_tbl neighbor entries are purged from the port.
