The motherboard is the place where all of hardware of the computer links to, including the USB ports. Sometimes the motherboard must be “rebooted” because things can fail, i.e. all or some USB ports suddenly stop working. The little microprocessor on the motherboard will refill the chauffeurs and your USB ports must hopefully be recognizing devices once again.

Nevertheless, if you are installing a USB printer, drawing pad, etc, then it might be worth downloading the driver for that particular device.

Method 3– Restart & Disconnect USB Devices

The next thing you can attempt is to detach all USB devices and after that reboot the machine. when you have restarted, attempt to link the USB device that was causing the problem.

If that particular USB port does not recognize it, attempt another one. If the device is recognized by a various USB port, there could be a hardware issue with one of the USB ports.

If no USB port recognizes the device at all , then keep checking out because it’s probably something else. The method 3 is very effective regarding the problem of usb device not recognized in the system.

Click okay and after that restart your computer system. Attempt to reconnect the USB device and see if it is recognized. If not, return to the power management tab for each one and inspect the box again. If it does recognize that device, then leave them uncontrolled.

Method 5– Connect Directly to PC

A good friend of mine ran into this issue and the cause ended up being his USB center. He only had 3 USB ports on his computer, so he purchased a center where he could link an extra 8 USB devices.

I think this proved excessive for his computer and it just started sporadically not recognizing various gadgets. After removing the center and connecting the device straight to the computer, it worked simply great.

We have not truly been able to discover any other option to this issue other than minimizing the number of products linked to the hub. Really, another option worked, but it implied having to purchase a brand-new USB hub with more power.

If you are dealing with this problem in Windows 8 or Windows 8.1, then you might be in luck. Microsoft company has actually released a repair for Windows 8 not spotting USB gadgets effectively. Ensure to install this hotfix if running Windows 8.

Method 7– Update the Generic USB Hub

If you are seeing the Unknown Device error in the Device Manager, you can then also try another thing. Open Device Manager and after that expand Universal Serial Bus Controllers.

You should see a minimum of one item called Generic USB Hub. On some computers, you may see 2, three or more of these. Right-click on the first one and choose Update Driver Software.

At this moment, the Device Manager screen need to refresh and either the unknown device would still be there or it might now be recognized. If it is still showing as not recognized, then you should repeat the procedure for each Generic USB Hub noted.

Method 8– Uninstall USB Devices

As a last option, you can also attempt uninstalling all USB devices from your system and after that restarting. I discuss this last since even though Windows is supposed to instantly recognize the USB controllers, hubs and devices immediately, it can sometimes stop working and you’ll wind up with no USB ports working.

I had a computer system with 6 USB ports and only one port would not work properly. I uninstalled whatever under USB Serial Bus Controllers in Device Manager and rebooted. Instead of re-detecting whatever, I was entrusted no USB port working, so beware when using this method.

Go to Device Manager and begin uninstalling each item from under USB Serial Bus Controllers. Prior to you begin with anything that is already working, uninstall the items with exclamation points or that are noted as Unknown Device.

Method 9– Uninstall Hidden Devices

By default, Device Manager does not show all devices that have been installed to the system. It generally only shows the ones that are presently connected. However, if you set up a USB printer earlier and now no longer use it, it will still be set up, however will not appear in Device Manager.

Certain concealed or ghost USB gadgets can cause conflicts with present USB devices and for that reason lead to this mistake. You can see surprise devices in Device Manager by very first opening a command timely and after that typing the following 2 commands:

usb device not recognized
set DEVMGR_SHOW_DETAILS= 1.
set DEVMGR_SHOW_NONPRESENT_DEVICES= 1.
start devmgmt.msc.
When Device Manager loads, you need to click View and after that click on Show Hidden Devices.

Now you wish to broaden the Imaging Devices, the Universal Serial Bus Controllers and the Unknown Devices. If you see anything listed there that is greyed out or that states unidentified device, go ahead and right-click on them and pick Uninstall. Hopefully, removing the older gadgets will allow the more recent devices to work correctly.

Other Possible Solutions

If absolutely nothing has worked till this point, it’s pretty safe to state there could be an issue with the real hardware. The best thing to do on that moment is to connect the device to another computer system and see if it works or not. If not, then it’s certainly a concern with the device.

Possible Solution # 1

The other possible services are to attempt a various USB cable television, if you have one lying around. If not, simply purchase a new inexpensive USB cable television from Amazon: A to B, A to Micro B, A to Mini B, or A to A.

This is a relatively uncommon problem, but I have seen it take place a few times over my many years doing technical support.

Possible Option # 2

Another possible service is to take the device, connect it to another maker and if it does acknowledge the device effectively, to then eject it effectively from that computer system prior to reconnecting it to the original computer.

I’ve seen this issue occur with numerous flash drives that were unplugged without ejecting correctly. After connecting them to another computer system and ejecting them correctly from there, they all of a sudden began to show up on the initial computer that was not acknowledging them.

Possible Solution # 3

A couple of people have had luck eliminating this issue by upgrading the BIOS. I have actually currently written a short article about whether it’s a great idea or not to update the BIOS, but in this case, it might be worth a shot.

You can likewise go into the BIOS and disable USB, restart the computer system and then enable USB again. The only thing you require to make certain is that you have a PS2 port on your computer system, otherwise you won’t be able to do anything once you disable USB in the BIOS if your keyboard and mouse are linked by means of USB.
