USB device is not detected or is malfunctioning

It’s not easy to troubleshoot a USB device, since they are usually plug-n-play devices. If your OS is Windows XP, it’s very easy to install and begin using a USB device; Windows XP has its own native drivers. But if your drive is not detectable, then the issue is probably hardware related. You could try the following steps to solve this issue:

1. Sometimes the problem is solved by simply unplugging it and plugging it back firmly. It can be a case of loose connection.
2. Try restarting your computer with the drive plugged into the USB port.
3. Some times there is a voltage drop across the USB port which also can be responsible for the problem. Simply wait for few minutes it will be detected automatically.
4. If all these attempts are useless, go to the "Device Manager"- Right click on my computer icon desktop and click on "Manage >> Device Manager".

• Expand the Universal Serial Bus Controller List.
• You can see an exclamation mark. Right-click on it and then click on "Uninstall".
• Now, Right-click on "Universal Serial Bus Controller" and click on scan for hardware changes. Now your USB device must be detected.

If all these attempts have not solved your problem, then probably you device is malfunctioning.

Fix the Problem Ejecting USB Mass Storage Device error

This must have happened to each of us many times that when we click the “Safely Remove Hardware” icon in the system tray to remove hardware, we get an error message saying “The device ‘Generic Volume’ cannot be stopped right now. Try stopping the device again later”.


One of the reason for this problem may be that the pen drive is still in use and some data is either being read from it or being written into it. That means some process is using the drive but we do not know what the processes are that are accessing the drive.

Steps to Fix the Problem Ejecting USB Mass Storage Device:
1. End the processes that are using the USB drive:
Download and install this software called as Unlocker, now open My Computer, right click on your USB drive icon, click on Unlocker.


Now click on Unlock All to kill all the processes using the Drive. Now the drive should get safely removed.

2. Clean the system infected by viruses:
If the first step fails that means the process that is accessing the pen drive is a virus for sure. So to clean the system just scan the computer with a good updated Anti Virus and delete the viruses that are found. The problem would certainly get solved.
