Re: high speed with low speed USB port?

There are 2 types of USB specifications. These are 1.1 and 2.0.


USB 1.1

PC purchased before 2001 are mostly used USB 1.1. USB 1.1 has a 12mbit maximum transfer rate.


USB 2.0

USB 2.0 is just like USB 1.1, but with much higher bandwidth. It will look the same and behave the same, but with a larger choice of more interesting, higher performance devices available. Also, all of the USB eripherals the user has already purchased will work in a USB 2.0-capable system. USB 2.0 has a 480mbit maximum transfer rate. Microsoft Windows will list USB 2.0 ports as Hi-Speed.


You can perform your activity with older USBs but transfer rate will be lower.
