I mention this last due to the fact that despite the fact that Windows is supposed to instantly identify the USB controllers, hubs and gadgets instantly, it can often fail as well as you’ll end up without any USB ports working.
I had a computer system with 6 USB ports and also only one port would not function correctly. Uninstalled everything under USB Serial Bus Controllers in Device Manager and restarted. As opposed to re-detecting every little thing, I was entrusted to no USB port working, so be careful when utilizing this technique.
Go to Device Manager and also begin uninstalling each product from under USB Serial Bus Controllers. Prior to you start with anything that is already working, uninstall the items with exclamation points or that are detailed as Unknown Device.

Certain concealed or ghost USB tools can cause conflicts with existing USB devices and also for that reason lead to this error. You can check out concealed gadgets in Device Manager by initial opening a command timely and afterwards typing the adhering to 2 commands:
- established DEVMGR_SHOW_DETAILS= 1.
- set DEVMGR_SHOW_NONPRESENT_DEVICES= 1.

Now you want to increase Imaging Devices, Universal Serial Bus Controllers and also Unknown Devices. If you see anything detail there that is grey out or that says unknown gadget, go on and right-click on them and select Uninstall.

Other Possible Solutions
If absolutely nothing has actually functioned until this factor, it’s rather safe to state there could be an issue with the real hardware. The very best point to do is to attach the device to another computer and see if it functions or otherwise. Otherwise, after that it’s definitely a concern with the tool.
Feasible Solution # 1– The other possible solutions are to attempt a various USB cable, if you have one lying around. If not, simply purchase a new affordable USB cable from Amazon: A to B, A to Micro B, A to Mini B, or A to A. This is a relatively unusual issue, but I have seen it occur a couple of times over my years doing technical support.
Feasible Solution # 2– Another feasible solution is to take the device, connect it to another maker as well as if it does acknowledge the gadget appropriately, to then expel it appropriately from that computer system prior to reconnecting it to the initial computer. I’ve seen this problem occur with numerous flash drives that were disconnect without ejecting properly. After linking them to one more computer and ejecting them correctly from there, they all of a sudden started to show up on the original computer system that was not acknowledging them.
Possible Solution # 3– A few individuals have had good luck doing away with this trouble by updating the BIOS. I’ve already written an article concerning whether it’s a great suggestion or not to upgrade the BIOS, but in this case, it might be worth a try. You can also enter into the BIOS as well as disable USB, restart the computer system and after that make it possible for USB device not recognized again.
