主機板的USB2.0沒有趨動!!
 

各位大大好:
小弟的主機板是陞技的AN8，用的是NVIDIA的晶片。
當初灌好之後，用主機板附的安裝光碟要趨動USB2.0的時候，跳出一個訊息說我需要先安裝XP的SP1，問題是我早就已經安裝到SP2了，所以沒辦法趨動…

因為一直以來也只是接USB滑屬或傳傳數位相機的照片，所以感覺影響不大…
直到最近用2.5吋硬碟透過USB在傳輸大量的資料才發現速度真的是慢啊…而且每次右下角都會出現訊息說「這個裝置可以執行的更快…」，殘念…

請問有沒有辦法抓到我的主板的USB2.0趨動程式啊???不然明明有這個功能卻沒法子用很嘔呀!!!

XP SP2應該都有支援USB2.0的規格
你有安裝NVIDIA晶片驅動嗎?
"nForce4 Chipset Driver"
ftp://ftp.abit.com.tw/pub/download/d...7win2kxp32.zip

只要有升級XP SP1以上應該就OK了
你是插機殼前面的USB擴充埠，還是主機板後面的USB埠？
試著直接插主機板上的USB埠
我先前插我機殼的有時會遇到你這問題、有時還抓不到＝ ＝"
直接插後面就都沒問題(盡量別透過延長線試試看)

沒錯，WIN-XP SP1就支援USB2.0無需額外安裝
你要注意的是主機板上用延伸線連接到機殼面板的
孔有時候會因為廠商偷工減料用"不符合USB2.0規
範"的纜線連接，導致無法以USB2.0高速模式運作..

或者說你BIOS中只開啟USB1.1模式，沒開啟2.0
運作模式...

我前置二個usb孔和主機板上四個usb孔都試過了，速度都只有1.1的規速…
BIOS我也有去確認過了…USB2.0是有開啟的…

奇怪，它訊息顯示說「您必須安裝一個高速的USB控制器，才能讓您的硬體發揮最大效能」
什麼意思啊???

你去裝置管理員看"通用序列匯流排控制器內"有無驚嘆號?
或者把圖抓下PO來看看...

你安裝xp時安裝的nForce4晶片驅動程式是用網路下載的?
還是包裝內光碟的?更新它看看..

也有可能是USB2.0沒有裝設完全。小弟以前也碰過類似狀況，
裝了2.0但不能發揮功用，因為得過且過心態，也沒注意去要求，
後來有一天裝新印表機，半夜三更工作過度，迷糊中點錯圖標，
在控制台裡點選「加入新的硬體」，竟赫然跳出裝設USB2.0的畫面，
自此以後，2.0就可以用了。
小小偏方，僅供參考。
