I have a problem with my GPX ML648S mp3 player. I synchronized a song onto it and it worked fine. I then unplugged it. A few minuted leter, I plugged it back in at this point the computer said the "it says usb has malfunctioned". I unplugged the player once more to find that it is now stuck on the "charge" screen (despite not charing; the litle batter icon appears to be frozen as well) and will not shut off. The computer no longer recoginizes the device despite restarting the computer. I have hit the reset button on the back of the mp3 player and I have clicked all buttons on it in an effort to shut it off, but its still stuck on the charge screen. Please help me?

SOURCE: cant get it to charge

I tried to reset and it didn't work, They way I figured out was to shut it off then plug the USB in. Then the screen shows up where it is sleeping, Then hit the power button one time and in the bottom left the USB light came on and in the top right you can see your battery taking charge. Hope this helps, It took me about three weeks to figure out

SOURCE: I am not able to put videos on my GPX ML648S 2Gig

If your player is still functioning for music, than it doens't need to be formatted. the video file you are trying to transfer needs to be converted.
follow these instructions to ensure a working video file.
Video files must be .AMV formatted to work on this MP3 player. Below is a link to a converter. It’s FREE and will convert your entire file.

Once you have the video files formatted to .AMV

1. plug your MP3 player into the computer
2. go to MY COMPUTER
3. find your .AMV video
4. Drag file to Scroll Bar on the left, hold the file over the GPX DEVICE
5. two folers will appear under it. Put file into ALBUMS

SOURCE: looking for drivers for gpx ml648s where do i find

I have not been able to locate drivers for this device either. All I can suggest is a manual reset. there is a small hole in the back of the mp3 player. Stick a pen into the hole and reset the device. This worked for me, but may not work for everyone. Sorry I can't be of more help.
