“Windows Cannot Recognize USB Device”

Asked By 40 points N/A Posted on -

I am having issues on plugging in my USB device on my Windows Vista PC. The device can be recognized when I plugged it since I can see it in Explorer. However, when creating a folder on the USB flash or save a file, I was unable to do it. When looking at the Explorer, the file which I just saved on my device is not visible. Even the folder which I just created. I tried the USB on another computer and it works perfectly fine. But not on my own PC. How can I fix this?

Since you already checked your USB device on another computer without any issues, the problem is probably on your computer. Try the following workarounds below:

1. Uninstall and reinstall the drivers for your USB.

2. Perform a System Restore.

3. Go to your Device Manager and then uninstall the devices on the USB Controllers. Restart your computer and it will automatically be reinstalled.

4. Unplug your computer from the wall outlet. And then start it again and see if it fix the issue. Modern computers doesn't really close when pressing the power button. So to reboot everything including your motherboard where the USB devices can be connected, try to close your computer and unplug from the power supply.

5. Click Start> Control Panel> System and Maintenance and then go to your Device Manager. Double-click the USB Controllers and see if the USB ports or hubs, and controllers are working. If they are malfunctioning, they will have an exclamation mark in front.

6. You may also disable the power management of your Hub. To do this, click Start> Run> Type Devmgmt.msc and click OK. This will open the Device Manager. Expand the USB controllers and then right-click on the USB Root Hub and click its Properties. It will open the USB Root Hub Properties box. Under the Power Management tab, untick the "Allow the computer to turn off this device to save power" check box. Click OK and repeat the same steps on each hubs. Then click Scan for Hardware changes so Windows will recognize the new device.

7. Restart your computer.
