請教如何確定 USB 2.0 已經 work ?
 

請教版上的大大:
我的版子晶片組是 nFORCE4, XPSP2 也灌了 USB 2.0 的驅動程式, 但在檔案傳送速度上與
USB 1.1 似乎沒甚麼差別 ! 在裝置管理員內也看不出名堂, 想請教如何確定 USB 2.0 已經
work ? 謝謝

請問您是使用哪些USB裝置呢？

nForce4晶片組支援的USB2.0在你安裝SP1(2)之後就會被正確的辨識出來，
無需額外安裝驅動程式.....

以檔案傳輸速率上，如果以隨身碟來講"我個人"可以感覺的出來USB2.0/1.1
運作模式的差異，前者速度快後者慢。

請告知你USB設備有哪些，然後用哪邊的Port連接USB設備?是主機板內建的?
還是機殼面板的?甚至是透過USB延長線或者USB HUB?

謝謝大大的回答, 我用的東西是普通的拇指碟 (USB 2.0) , 比較沒灌驅動跟灌了驅動之後傳檔的差別 , 將近 200M 只差五秒
主機板是技嘉的 GA-K8NF-9 , 拇指碟插在機殼前面板 ( 用排線從板子接到機殼 )
感謝版大告知 XP2 會自動辨識, 只是因為技嘉附了 USB 2.0 的驅動, 所以我就灌了一下
1. 裝置管理員裡 " 通用序列匯流排控制器 " 在灌驅動前後都是一樣
Standard Enhanced PCI to USB Host Controller
Standard OpenHcd USB Host Controller
USB Root Hub
USB Root Hub
驅動程式都寫明是微軟, 並沒有因為弄了技嘉的驅動而改變 ( IDE 就會變成是 nFORCE )
我想是技嘉唬爛吧
2. 我會試著把拇指碟直接插在板子上再試試是否有差
3. 或許這一點點差別( 五秒 ) 根本就是正常的, 只是我錯誤的期望太高了
謝謝大家的熱心

隨身碟安裝到主機後方主機板內建的port就會有差異了...
因為你機殼面板前方的port其USB Cable可能沒有符合
USB2.0規範...

謝謝版大指點, 剛試了一下 , USB 2.0 的拇指碟 , 222 M , USB 到 PC , 前面的 port 約 65 秒 , 後面的 port 約 50 秒 , PC 到 USB 則要 5 分鐘 . 改用 USB 1.1 的拇指碟, 同樣的檔案則等得快打瞌睡. 這樣看 USB 2.0 應該是有起來 , 感恩版大指點. 明天去弄一條合規格的線, 不然後面的 port 實在不好搞

五秒的差距並不大
可能是傳檔的時候，同時執行了哪些程式吧
不然 USB 1.1 與 USB 2.0 的差距可是差了12倍^^a

謝謝樓上大哥的指點, 沒錯, 我用 2.0 跟 1.1 的拇指碟分別傳檔 (當然不是很精確), 打了一陣瞌睡後 1.1 還在傳, 所以我就去睡覺了 : 感覺不太一樣的是 USB ==> PC 和 PC ==> USB 的速度差別很大

NAND Flash Memory本來讀寫速率就不同，仔細體會就感覺的出來....

USB裝置本來就有很多顧慮，HUB與纜線都會影響到傳輸效能，就以
機殼前方面板來說，很多機殼其前方的port大多使用不符合USB2.0
規範的纜線連接主機版端，導致其效能只有1.1。這是最常出現的狀況
，使用時系統會提醒你"高速裝置安裝在低速介面".....:decfghi6:


像我買隨身碟時故意挑有附贈延長線的款式，我把線貼在機殼上就等於
有一個從後方引來前方的port了:ddrf567h:

老大..這套軟體有沒有特別版阿?:ddrf567h:
小弟找好多要測USB的軟體都找不到說@@

USBTrace V1.3.0 註冊版

USBTrace is an easy to use and powerful USB analyzer. USBTrace can monitor USB transactions at host controllers, hubs and devices. This is a 100% software product. USBTrace supports Windows 2000, Windows XP and Windows 2003 Server operating systems and works with USB 1.x and 2.0 (low, full and high speed) host controllers, hubs and devices.

USBTrace Features
USBTrace is an invaluable tool for all those who develop firmware and drivers (WDM) for devices which connect to the PC using the Universal Serial Bus.

Ease of use
With USBTrace you can monitor your devices very easily. Just select the device to be monitored and click 'capture'.

Monitors USB requests at all levels
With USBTrace you can monitor USB requests at USB Host Controllers, USB Hubs and USB devices.

USBTrace does not use any filter drivers
Unlike other software analyzers, USBTrace does not use any filter driver to capture the USB requests. So USBTrace will not disturb the PnP system due to its presence.

Captures all USB requests during device enumeration
USBTrace is capable of capturing all USB requests exchanged between the host controller/hub and the device during device enumeration.

Displays valuable information for WDM device driver developers
The IRP, URB and IO_STACK_LOCATION structures associated with each captured request is decoded and displayed by USBTrace. Also, in addition to capturing URBs, USBTrace captures Internal USB IOCTLs, User mode USB IOCTLs, PnP and Power IRPs.

USBTrace also allows WDM driver developers to capture USB requests made/received by any device object in the USB device stack.
