8 Reasons Why USB Device Is Not Showing Up & Corresponding Solutions
1. USB device is damaged physically: convenient as USB flash drive is, it often damaged by frequent plug in and out, magnetic interference, high temperature and other factors.
If your USB device encounters hardware failure, you can check the broken component and replace it with a new one or turn to professional recovery companies to recover data from it.
2. USB device is disabled in CMOS: this situation is commonly seen in public places like café, net-bar, school computer room and office. USB interface is disabled for the safety of computer; it's very understandable.
Enter CMOS -> find USB device from related setting items in motherboard -> change the state from disable to enable.
3. USB driver is not installed properly: this is considered as one of the most widespread failures occurred on USB flash drive device. After the USB device was inserted into computer, the system will prompt "Found New Hardware" and start to install the driver.
However, if we cancel the installation process for feeling risky or troublesome, it will lead to failure in loading USB drive normally. Thus, this USB flash drive can't be recognized by system.
Open Windows Disk Management -> refresh corresponding interface to see whether the USB drive will be reloaded and reinstalled or just find the USB device with a question mark -> right click to uninstall it -> reconnect USB device to computer to install.
4. The OS (Operating System) used in computer is excessively simplified: in general, the built-in driver package of common Microsoft OS already contains a lot of drivers approved by Microsoft. So, it's able to identify many device drivers automatically, of course, including USB device driver. Nevertheless, in various simplified versions of Windows OS, the corresponding drivers are also simplified.
Find the official driver or make use of a third-party driver tool.
5. The power supply of USB port is not sufficient: each USB device can only work normally under certain power supply conditions. If the USB port provides insufficient power supply, those signs will appear – the USB indicator does not flash or its state is abnormal; system fails to boot as usual after USB device is connected to computer; the content in USB device can't be accessed or the access speed is much slower than before.
Change a USB port or provide separate external power supply to USB device. Or when choosing from various USB flash drives, you could buy a low-powered one.
6. The drive letter assigned to USB flash drive has been already occupied by another drive in computer: if "J" is assigned to your USB flash drive, but now you connect it to a computer in which the drive letter "J" is used by another local drive, drive letter conflict will be caused at this time. And it will prevent your USB drive from being recognized by this computer as an available storage device.
Install MiniTool Partition Wizard to computer -> run it and right click on USB drive -> choose "Change Letter" function -> assign an unused drive letter to the device under guidance. Or you can choose other partition management tools to finish this.
7. Manufacturers of the newly installed USB device used unconventional flash memory chip and technology to make the flash drive: this situation can be mainly divided into two types.
One is that in order to protect their own chip technology, some large companies choose to use non-standard chip or encrypt data read and write mechanism; or they just decide not to share chip parameters with others, stopping USB driver writers from writing corresponding driver. The other is that some small companies or illegal small workshops create their USB device with inferior-quality fittings.
Go to manufacturers' official website to download the latest USB driver package or find the original CD driver.
8. Virus attacked USB flash drive: if your flash drive was exchanging data with other devices which are infected by virus or some of the files you saved in the flash drive contains virus, it is very possible that this drive can't be detected successfully. This is because virus may damage the driver or files which are needed for the normal working of device.
If virus is detected in flash drive, you'd better seek ways to recover data from USB device before trying to kill virus with powerful antivirus program.
