We bought my son an RCA mp3 player yesterday (TH1814-A). We inserted the battery and are trying to plug it into my desktop using the usb connector so that we can upload some music. however, when i plug...


There are different types of USB port. For instance my computer has two types. One with a blue connector and one with a black connector. It might be that your USB ports are not suitable for that device. You need to check the specifications of the USB ports on your computer and the specifications of the MP3 player. Continuing to use the device might cause damage to the computer.

1. Click "Start", type in Device Manager the Search bar and press "Enter". Click Continue if necessary.

2. In Device Manager, double click to expand "Universal Serial Bus controllers", right click on the "Host Controller", click "Uninstall" and click "OK".

Usb ports not recognized


Did this suddenly start to occur? Were they working before? If so, it is very simple - shut down computer, remove the battery and unplug any power source, wait a couple of minutes and reassemble and power up. Wala! I read all kinds of complicated instructions, started with the simple, and problem solved.

Do you have anything like a printer or scanner or an external USB drive connected to the computer. If yes, then remove it. If not let me know.
