36. Cannot be detected by the computer? Why? And how to solve it?
Several factors can prevent Windows from recognizing your portable device. If Windows doesn't
recognize your portable music player, it could be a corrupt or missing device driver. In this case,
resolve the problem by reinstalling or updating the driver. Sometimes connection problems that
aren't driver-related can be fixed by upgrading the portable's firmware, particularly on older
devices with known issues.
Please check the description below to identify problems.
Normal checkups
1) Make sure that the drive is properly plugged in to your computer.
2) Try different USB port of the computer. If you’re using a desktop, we suggest you to try the
rear USB port.
3) Try another USB Cable.
4) Reboot the PC.
5) Connect the mp3 player to the PC while holding the play/pause button.
These steps should allow the player to be read by the USB port correctly and will show the player
in "My Computer" as a new drive letter.
Still not working?
Try updating the USB drivers.
Press Windows key + R. This will open Run. Alternatively, you can go to Start and search for ‘Run’.
In Run dialog box, type ‘devmgmt.msc’ and hit enter.
Go to ‘Universal Serial Bus controller’ and expand it.

- 15 -
Right click on the ‘USB root hub’ and click on update drivers.
Click on Search automatically for updated driver software.

- 16 -
Restart the PC after the updating of the drivers completes.
Unknown Device in Windows
Right-click Start, then select Device Manager from the list.
Scan the list of devices. Check to see if an unknown device displays. An unknown device has a
small warning triangle overlaying the device-type icon.
A red icon overlay indicates a device is broken or non-responsive.

- 17 -
If you discover a warning icon, right-click the driver and select Update driver to install the correct
driver.
You may need to install the manufacturer's software to ensure that the correct drivers load.
Update Windows
Make sure your version of Windows is up-to-date. Ensuring your operating system remains
current with application and security patches can sometimes fix a compatibility problem.
Select Start > Settings.

- 18 -
Choose Update & Security.
Select Check for updates to verify that your Windows 7/8/10 computer is fully patched. If it isn't,
install the recommended packages then, if necessary, reboot the computer.
Try a Different USB Mode
Set the portable player to use a different USB mode if the unit supports it:
Disconnect your portable from the computer.
Look in the portable's settings to see if you can select another USB mode, such as MTP mode.
Connect the portable again to the computer to see if it is recognized.
