How to Solve USB ‘Device Not Recognized’ on PC

Surely you often experience an unreadable flash drive on your PC? Usually the flash is damaged or there is a shortcut virus on the flash. Apart from flash drives, there are also other USB devices such as smartphones which are also unreadable on a PC.

Usually this USB device appears a notification ‘Device Not Recognized’ aka the device is not recognized by the PC. But don’t worry, guys, it turns out that there is a way to solve USB Device Not Recognized on PC. So, take a good look!

Causes Device Not Recognized Appears When Connected to USB!

Before discussing how to solve a USB Device Not Recognized, it would be nice if you first knew the cause of the notification, by listening to the following points!

1. Most Built-in USB

The most common cause is that the available USB port is being used too much or too many USBs are plugged in. Because usually the unreadable USB is because the USB hub does not have enough electrical power.

Given the number of USB connected, so the power will be shared with others. Therefore, make sure you connect the USB as necessary.

2. Origin Unplug the Connected USB

Surely you often connect smartphone devices or flash drives using the USB port on your PC or laptop? Yups, sometimes we unknowingly after using it, just unplug it without having to eject the port first.

If this is done continuously, it will cause the USB port to experience bad sectors or errors so that the ‘Device Not Recognized’ notification appears.

Not only that, even if you immediately unplug a device such as a flash drive from the USB port, it is likely that the flash will also experience errors such as a flash drive that asks for format.

3. The System is Error

Next it could be because your PC or laptop system is in error or in a problematic state. If the system is having problems or errors, then do not be surprised if other components also have problems.

Not only the USB port is affected, but there are also those affected by the folder that cannot be opened. Usually this problematic system is due to virus infection, failed Windows updates, configuration errors and so on.

4. USB Driver Problem

As we know, every time there is a problematic driver. Then the system cannot run the software properly. Moreover, the driver function is a component that connects the system with the hardware.

If the driver is in trouble or has not even been installed, then the hardware components also cannot function properly.

Just like when a laptop speaker doesn’t make sound, it’s possible that the USB ‘Device Not Recognized’ notification appears because the driver hasn’t been updated or hasn’t even been installed.

5. Damaged USB Component

The last possibility, could be because there is a damaged USB component. Fair isn’t it? If any hardware is damaged, especially on the USB port, it can make the system not detect the connected port.

Usually this is because there is a disconnected cable in the USB port, it could be due to dust or even exposure to water. Even though it’s generally human error, some are damaged by factory defaults, guys!

“Then how to solve the USB ‘Device Not Recognied’ notification appears?”

Quiet! Just take a look at the following steps.

Oh yes, we have also discussed how to restore deleted files on a flash disk, guys, how to use a recovery application. Eh but we don’t talk about that, we will discuss how to solve the unreadable USB Device Not Recognized below!

1. Unplug the Power Supply

The first way to solve USB Not Recognized on a PC is to unplug the power supply. Usually behind the CPU there is a cable that is connected directly to the power supply.
