USB device errors not recognized as “Unknown device ” or “USB device not recognized ” are very common problems that PC users will encounter sooner or later. There are several causes that contribute to these errors, including defective devices and damaged USB device drivers. We will discuss several possible solutions to choose from if you are experiencing a problem now or want to prevent these problems from occurring in the future.
There are two main categories of problems attaching unknown USB devices: manual options and the Instant option. First, consider the manual options.
The manual troubleshooting options of unknown USB devices vary depending on the causes and approaches, but to begin with, we will consider the two basic options.
Reconnect the USB device:
There are some cases where a properly functioning USB device stops working suddenly. This unknown USB device error can be easily resolved by unplugging the device and plugging in a USB port again. This option is true for portable USB devices and other Plug and Play devices.
Restarting the computer:
Except for defective devices, some USB devices will not function properly unless you reboot your computer after installation. To resolve this issue, you must restart your computer to establish a proper connection and initialization between your computer and the USB device.
The first two manual solutions can only be effective for repairing defective device connections and incorrectly installed USB devices.
The following solutions will work primarily for problems with unknown USB devices caused by damaged or missing USB device drivers.
Reinstall USB Device drivers:
Reinstalling USB device drivers can also be a basic option if the required device drivers are already available on your computer or if the installation CD is still available. You can run this solution by following these steps:
Right-click the unknown problematic USB device that appears in the Device Manager window.
Click “Update ” and follow the installation wizard.
Throughout the process you will be asked if you still have your installation CD, and if you do:
Insert the CD
Select the option “Install the software automatically (recommended) “
Click “Next “
From this point on, the installation will continue automatically and you need to install the necessary drivers.
Having an installation CD will be very useful, but if you do not have the installation CD and the problem persists after attempting to reinstall the device driver, then you could try to search online for the device driver to solve your problem Unknown USB device. For this you will need the identification numbers of your device. To be able to collect this data, return to the properties of the unknown USB device problematic by passing through the following steps:
Right click on the unknown USB device problematic
Mark the tab “Details “
From the drop-down list, locate the “device instance path ” or “device instance ID “
The alphanumeric data provided, such as USB | VID_0951 & PID_1623 | 00137298f25ba1140000011, it will allow you to search the device driver online. The necessary information in this example is the vendor ID or VID with a value of 0951 and the PID_1623 or product ID with a value of 1623.
Only the use of the Internet already invites the risks to your computer, so what about finding the device drivers and downloading them? You may end up downloading outdated device drivers that can worsen the functionality of your USB device, damaged drivers that will make your device malfunction, or USB drivers full of free gifts-viruses like Trojans, Adware and spyware .
