Nothing Happens When I Plugged in USB

"Nothing happens when I plug my USB flash drive into the USB port. It's showing up nowhere and Windows doesn't even prompt any error message. How can I find or open my USB drive in this case?"

Let's clarify that solutions to such an invisible USB device problem on this page vary from those of computers not detecting or recognizing a USB flash drive, which is usually with some supplementary information. The informative messages are as follows.

• "USB device malfunctioned and not recognized" in the Windows system tray icon
• File system displays as RAW in Windows Disk Management
• "Unallocated space" in Windows Disk Management
• "Unknown device" in Windows Device Manager

Since this problem is different from the above situation, what should you do when you encounter this problem? On this page, we list some valid solutions. But at first, we will introduce the reason why nothing happens on your computer when a USB is plugged in.

What're the reasons

Human errors and hardware issues are taken as two major reasons why your USB fails to work fine like it used to do. Let's check the more detailed reasons.

1.Human errors

This one is a common mistake that users usually make. The USB device was abruptly unplugged without safely ejecting at the last time it was used on the computer. This would result in theexternal hard drive not being recognized after unplugging.

The hardware issue is a pretty wild concept. The most common hardware issues include the following ones:

• The USB drive is broken and dead
• There's a problem with the USB port
• There is a problem with the USB driver
