沒錯..樓上為正解....(恕刪)
錯很大...其實USB1.0, 1.1, 2.0指的都只是SPEC.的版本, USB1.0的時候只有low speed:1.5Mbps的規格
到了USB1.1加入了full speed:12Mbps的規格, USB2.0這一版加入了high speed: 480Mbps的規格
USB2.0=high speed
USB1.1=full speed
USB1.0=low speed
上面這幾種講法是我們一般大眾為了容易區分的講法...事實上USB2.0裡面三種規格都有, 不能說USB2.0就等於high speed或full speed

Full Speed 不是 USB 1.0
而是 USB 1.1
USB 1.0 => 1.5 Mbps
USB 1.1 => 12 Mbps (Full Speed)
USB 2.0 => 480 Mbps (Hi Speed)
目前BIOS中USB1.1和真正的USB2.0都泛指为USB 2.0
用Full Speed和Hi Speed區分
錯了

USB 1.0: Released in January 1996.
Specified data rates of 1.5 Mbit/s (Low-Speed) and 12 Mbit/s (Full-Speed). Does not allow for extension cables or pass-through monitors (due to timing and power limitations). Few such devices actually made it to market.
USB 1.1: Released in September 1998.
Fixed problems identified in 1.0, mostly relating to hubs. Earliest revision to be widely adopted.
USB 1.0 已經定義了 Low Speed 和 Full Speed。
USB 1.1 只是修正一些問題。

full speed 和 low speed 的規格是在 usb 1.0 中即有定義的規格，usb1.1中有作修改。
