My mp3player isn't recognized by my computer.

Check the player when it is connected to the USB port, the player mode can be changed between USB or MTP. it must be on USB for the pc to recognize it.

OK, this problem was driving me almost to tears with frustration but have managed to bodge-solve it so hope this helps!

Right click My computer and select Properties.
Click on Hardware tab.
Click on Device Manager.
Hopefully there is a yellow question mark symbol against Iriver T30 listed under other devices or portable devices or something.
Right click this then select Update Driver.
Tell it that you are going to manually update the driver yourself.
Eventually you will have to select what type of device it is - select portable device.
Now click on MTP device and click next to install the driver.
Hopefully now it is recognised by XP in My Computer....

Good luck

I got the same problem and the above link fixed it.
The reason this occurs is because you need to
update the firmware of the iRiver T30 to the latest version.
Just go to the above link and unzip the file it tell you to
and simply run it, it will give you a menu and the software will do the rest. Lastly don't worry if you only get 50% done message, as
leave it for 10 minutes then disconnect the usb cable and take the
battery out of the T30, put it back and presto, my computer can read the T30 folder. You can use the library in Windows media player or just copy and paste from Windows Explorer, you can copy back and forth as you please. Enjoy.
