USB 2.0
All of the USB devices themselves as Hi-speed. USB 3.0, is the recent hi-speed USB.
A high-speed USB (2.0) has a raw data rate at 480Mbps, and it is rated 40 times faster than 1.1.
High Speed usb is 2.0 now some comptuer have a 2.0 speed usb port some are slower. So if it says "You have plugged in a highspeed usb to a slower port" Or w/e then that means it will just be slower. Newer / Old but expensive comptuers have high speed USB ports. Hope this helped
Hint hint... high speed

12 Mbps for original and 480 Mbps for high speed.Darryl Erickson
A USB host controller is a piece of hardware. It is usually incorporated into the southbridge in your motherboard. As such, it cannot be downloaded. If you want to upgrade a low-speed USB controller to a high speed controller you will have to buy a new high-speed controller. Changes are the old controller is not removeable and not upgradeable.
Super Speed USB is faster and is usually identified by a blue port or wire. Basically USB 2.0 is High Speed (480Mbps) and USB 3.0 Super Speed (5Gbps).

Up to 480Mbits/second, and being increased over time with improvements.
