Try this, uninstall ALL software and Drivers to do with the Player. Reboot. Then reinstall all the software and drivers again, then plug in ya player into ANY OTHER USB port and it should be detected and work.. If not.. its repair/replacement time :(

Not sure if player is charging

Can you see it in "My Computer"? It will show under "Removable Drive/Storage"

Double click the removable drive to open the folders. Can you see your music, photo and movie folders?

Can you see the player in Coby Manager - under the "DEVICE" tab?

When disconnected from the computer, how long can you listen to the Coby player before it goes off?

If not present in My Computer or in Coby Manager/Device Tab, then it is not plugged in correctly.
a. Disconnect the player from the computer.
b. Wait for it to cycle through "Please Wait" and "Updating Library" screens.
c. Make sure the player is TURNED OFF
d. With player TURNED OFF, reconnect wire to the player then to the computer.
e. You will see a USB connector icon on the player screen and the player charging.

It will appear to be charging all the while it is connected to the computer.
After it has been plugged into the computer for an hour, it should be well charged unless the battery is completely run down. In that case, you need to do an initial 8 hour charge - with the coby player OFF - through the computer. (This one got me when I first got my player!)

f. Use the Coby Manager to disconnect the player (Found HERE CobyMedia Manager fix for MP822 (Windows XP/2000/Vista)

1. Open Coby Manager
2. Go to the DEVICE TAB
3. CLICK on EJECT Button in lower right hand corner.
4. It will have a pop-up screen to ask "Do you want to eject?" Click YES.
5. The second pop-up screen will tell you "The device can now be safely removed from the system."
6. Disconnect the player from the computer.
7. The Coby will now show "Please Wait..."
8. It will take the Coby about 10 minutes on the "Please Wait" screen and then on the "UPDATE the Library" screen - Be PATIENT

You should now have enough battery power to use it. To check the battery level,

1. Turn on the player
2. The battery icon is in the upper right hand corner of the screen - it is ALWAYS RED until it starts to go down... I've not had mine down very far, but believe the red line gets shorter as the battery is wearing down.

Hope this helps.

If you have deleted the program from your computer, you should be able to plug the Coby player (TURNED OFF) to the computer and re-install it.

If Coby Manager program is no longer on the Coby player (If you re-formatted the player), you can get a copy of the MANAGER here:

CobyMedia Manager fix for MP822 (Windows XP/2000/Vista)

Don't let it throw you that it says it's for the MP822 - it also works great for the MP610

1. Install Coby Media Manager from download

2. Open Media Manager

3. Plug your COBY player (THAT IS TURNED OFF) into the USB port - it will show up in the "DEVICE" tab

Voice recorder function or not?

When you turn on your mp3 and there's the list like music, movies, ebook... etc... choose the Record and when you get to rec. push the options button (OPT top right had corner) then start record, then when you're done push pause/play and then turn off the mp3 and then go back to the record mic again and push play to listen to it.
