You can access Device Manager by clicking Start and typing in devmgmt.msc or simply by going to Control Panel and clicking Device Supervisor .If That's the Case, you must right-click On Unknown Apparatus , click Properties, and then the Driver tab and click Update Driver.

If this does not work, you can even Attempt to get the driver for your device from the company's web site. When the USB device is merely a flash drive, then it is likely not a driver problem.

The next thing you can attempt is to Disconnect all USB devices and restart the device. As soon as you've restarted, attempt to connect with the USB device that has been causing the issue.

If that USB port does not Recognize it, try a different one. In case the unit is recognized with a unique USB port, there might be a hardware issue with a few of those USB ports. If no USB port admits the apparatus, then read because it is likely something else.

Technique 5 -- Join Directly to PC

A buddy of mine ran into this dilemma Along with the cause was his USB hub. He just had three USB interfaces on his computer, so he purchased a heartbeat where he could join an extra 8 USB devices. I guess this was too much because of his Computer and it only started sporadically not comprehending a variety of apparatus. After eliminating the heart and connecting the unit directly to the pc, it worked just fine.

We have not been able to Discover Any other remedy for this problem aside from reducing the amount of things linked to the hub. In fact, another alternative worked, however, it meant having to purchase a brand new USB hub using more electricity .

As a last resort, You May Also attempt Assessing all USB devices from the machine and then restarting. I mention this past because although Windows is likely to automatically understand the USB controllers, devices and hubs mechanically, it can at times fail and you will get no USB ports working.I had a pc with 6 USB ports And just 1 interface wouldn't operate correctly. I uninstalled everything beneath USB Serial Bus Controllers in Device Manager and restarted. Rather than re-detecting all, I had been left without a USB port functioning, so be cautious when using this technique.

Proceed into Device Manager and begin Uninstalling each thing from beneath USB Serial Bus Controllers. Before you begin with anything that's already functioning, uninstall the things together with exclamation points or which are recorded as Unknown Apparatus .

Technique 9 -- Uninstall Hidden Devices

By default, Device Manager does not Show all devices which were installed into the machine. It essentially just shows the ones which are connected. But in the event that you set up a USB printer now no more use it, then it will nevertheless be set up, but will not appear in Device Manager.Particular concealed or phantom USB devices Can cause conflicts with all current USB devices and so cause the error. You can see hidden devices in Device Manager by opening a command prompt and then typing the following two controls:

1. 1. set DEVMGR_SHOW_DETAILS=1

   2. set DEVMGR_SHOW_NONPRESENT_DEVICES=1

   3. start devmgmt.msc

   4. After Device Manager loads, you Require To click View then click Show Hidden Device

Now you would like to enlarge Imaging Devices, Universal Serial Bus Controllers and Unknown Devices. Should you find anything listed there that's greyed out or says unknown device, proceed and click on on them and select Uninstall. Hopefully, eliminating the old devices will permit the more recent devices to operate correctly.

Additional Potential Solutions

Otherwise, simply buy a brand new cheap USB cable from Amazon: A to B, A to Micro B, A to Mini B, or A to Your .

Possible Option 2 -- Another potential alternative would be to take the device, join It to a different device and if it will recognize the apparatus correctly, then disconnect it correctly from that pc before reconnecting it to the computer. I have seen this problem happen with various flash drives which were unplugged without ejecting correctly. After linking them to a different pc and ejecting them correctly out there, then they suddenly begun to appear on the first computer that wasn't recognizing them.

Possible Option 3 -- Some Individuals have had luck eliminating This Issue by Upgrading the BIOS. I have already written a post about if it is a great idea or not to upgrade the BIOS, however in this circumstance, it may be worth a try. You might even enter the BIOS and disable USB, restart your pc and after that empower USB again. The one thing that you want to make certain is that you've got a PS2 port in your computer, otherwise you will not be in a position to do anything as soon as you disable USB in the BIOS if your mouse and keyboard will be connected via USB.
