Computer or Kies Does Not Recognize Phone Device

What to do if your computer does not recognize your Samsung phone or Android device every time you connect it through a USB cable?. There are times wherein your device driver becomes unidentified all of a sudden. Even Kies does not recognize your phone device. Sometimes, an error like this will occur:

USB Device Not Recognized. One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message.

These are the possible solutions for this specific issue or error:

1. Use other available USB port

If the system does not recognize the device, try to plug the USB cord to other USB port in the computer. Check if your phone is charging. If that’s the case, it means that there’s no problem with the cable or the USB ports.

If this is the first time that you plug-in you’re device to your computer, Windows automatically identifies the device and searches for the correct driver. If it fails, make sure that Windows Update is enabled. If it still cannot find the device driver, use Kies as an alternative (Solution #2).

2. Troubleshoot Connection Error through Samsung Kies

If you don’t have Kies installed on your PC, you can download it here. The device driver will be downloaded and installed automatically. Just make sure that your computer is connected to the internet. If the driver was installed successfully, Windows will show a notification indicating that the device is ready to use. You can verify if system now recognizes your phone by doing the following:

-Run Kies
-If Kies didn’t recognize the device, Click Troubleshoot connection error button.
-Click Start
-Let Kies identify the issue and fix it automatically.

Samsung Kies can troubleshoot connection error when Windows cannot recognize your Samsung phone or Android device.
Most of the time, Kies will just reinstall the driver to fix the issue. If this still doesn’t work, proceed to Solution #3.

3. Refresh your mobile device

Do this after you tried Solution #2 above. Make sure to close Kies before doing the following steps:

-Unplug both ends of the USB cable from both computer and the mobile device.
-Turn off your phone.
-Remove the battery and replace it again after 3 minutes. Do the same with the SD or memory card.
-Turn on your phone.
-Connect it again to your computer through USB cable.
-Run Kies and check if the device is now recognized by the system.

4. Reinstall both Kies and device driver (For those who have previous version of Kies installed on their computer).

Uninstall first the current version installed on your PC before installing a fresh copy of Kies. By doing this, Kies will be updated to the most current version as well as the device driver.

5. Use the correct USB cable

Make sure that you are using the original USB cable included in the box when you bought your phone. If you’re using a replacement, make sure that it is compatible with your device. If your phone is just charging every time you connect it to your pc, don’t jump to a conclusion that the wires responsible for data transmission are defective. If you have another computer or laptop, try to check if the machine will be able to detect the device. If not, you can try replacing the cable with a brand new one. Make sure that you’ll buy only the original.

I don’t recommend doing hard reset as a solution for the problem. You might regret doing in the end. If your phone is still under warranty, I suggest that you bring it in a service center and let the experts examine your phone. Also, regarding the USB debugging option on your phone, it can be a silver bullet. Once enabled, your computer should detect your phone’s mass storage automatically. The phone’s SD card will appear as a device with removable storage with a drive letter assigned to it.
