USB problem HI-SPEED USB Device in a non HI-SPEED port

My new mp3 player won't connect properly to charge off my computer from the USB port as it says, 'The MTP Device is a HI-SPEED USB device and will function at reduced speed when plugged into a non HI-SPEED port.' It says that I must add a HI-SPEED USB host controller to the computer. What is this and how can I get it? please help!

There are two versions of USB in widespread use today: USB version 1.1 and USB version 2.0. Version 1.1 is the legacy (older) version that can transmit data upto 11 Mbps, whereas version 2.0 is magnitudes faster. Your machine has a low-speed bus (as in, its USB ports are version 1.1). You can purchase a USB 2.0 PCI controller card that will allow you to have some high-speed ports. Then your MP3 player will be able to operate at full speed and charging should work fine.
