Hi,

Did you guys meet such a problem? When you access to an external USB hard drive, it says an error message:

USB Device not recognized: One of the devices attached to this computer has malfunctioned and windows does not recognize it

Is there something wrong with the USB device? Or does it mean something wrong with PC?

I have tried many times. How can I fix it? Thanks.

This issue can be caused by any of the following situations:

1. The currently loaded USB driver has become unstable or corrupt
2. Your PC requires an update for issues that may conflict with a USB external hard drive and Windows
3. Windows may be missing other important updates hardware or software issues
4. Your USB controllers may have become unstable or corrupt
5. Your external drive may be entering selective suspend
6. Your PC motherboard may need updated drivers.

Try to check if the situations exist and fix it.

Hi mirs, thanks for help. I have fixed it!

Did you have to delete the USB drivers from Device Manager and have Win 8 CP reinstall them or something else. The fix is important so others may know in case they have similar problems.

Hi please guide me how u fixed that.

You can try update your driver when meeting with such problem.

First, you can use Windows update.
Step 1. Swipe in from the right edge of the screen, tap "Settings", and then tap "Change PC settings". But if you are using a mouse, point to the lower-right corner of the screen and move the mouse pointer up. Then click "Settings" and "Change PC settings".

Step 2. Tap or click "update and recovery", and then tap or click "Windows Update".

Step 3. Tap or click "Choose how updates get installed".

Step 4. Under important updates, choose "Install updates automatically".

If it does not help, you can use a drivers update utility to update the driver automatically. With it, you can download and update whatever drivers whenever in need. tiny.cc/3cwerx. It helps me download and update many of my device drivers and I hope it can also work for you. You can download and install it, then it will automatically scan for your system and recommend suitable drivers for you. You can download or update whichever driver you need.
