USB2.0 driver installation full contact
In fact, many computers have not installed properly or not, most users do not really enjoy the pleasure of USB2.0, although USB2.0 has 480Mbps peak theoretical data transmission rate, including Lenovo, etc. brand computers and DIY Computers Users, or even random drive disc installations can not be installed.

Want to know if your computer works in USB2.0, you can right-click "My Computer" in Win98 and view "Universal Serial Terminal Controller" in Hardware Information in the Properties. Does USB 2.0, Windows XP Should be viewed in Device Manager on the hardware page of the system properties.
The reason for the above situation One is that Windows XP itself has some vulnerabilities, and it is necessary to upgrade first. Second, there is a compatibility problem in some chipsets and require certain installation skills. Third, the system setting does not set USB 2.0 to "enable", and there is a computer that sets a setting for USB2.0 mobile hard drive, which must be set to "enable".
First check whether the computer settings are set to "Enable" items on USB2.0.

"China Computer Education" Author: Yuan Jingtao http://www.fzsky.net
NFORCE2 users reflect the biggest problem is that USB 2.0 devices cannot be used normally, such as unrecognizable, copy file errors, mobile hard disk disappearance disappears. These are because there is no correctly installed NFORCE2 USB2.0 driver. The following is an EPOX 8RDA motherboard as an example to describe the installation method of the USB2.0 driver in the Windows XP operating system, which also applies to other brands of the NFORCE2 chipset.
First, install Windows XP correctly, play SP1 upgrade package
Windows XP Service Pack 1A can be downloaded at http://www.microsoft.com/china. SP1 can fix the vulnerabilities already in Windows XP to improve the security of the operating system.
Second, install the NFORCE2 chipset driver
NFORCE2 chipset common drivers have mainly 2.0, 2.03, 1.16, 3.13. From the experience of using the 1.16 version is the most stable, other versions are mainly used to speed up and solve compatibility issues. The latest 3.13 official multilingual version for Windows 2000 / XP (released on November 4, 2003), has passed WHQL certification, can be downloaded from http://www.mydrivers.com/dir79/d31945.htm.
It should be noted that the SW-NVIDIA IDE disk acceleration program is integrated in this driver, and Windows XP cannot be started after installing this driver on some motherboard, so "NVIDIA IDE SW" driver appears during the driver installation. Program installation information, click "Next", ask if "SW" is installed, "No" Skip (as shown in Figure 1). After restarting the computer as required, "Universal Serial Bus (USB) Controller" and four normal "general serial bus controllers" and four normal "general serial bus controllers" (eg figure 2). Third, properly install USB2.0 driver
1. Download, install the USB2.0 driver
2. The general motherboard drive disc does not include a USB2.0 driver, and the user can download the corresponding driver to the motherboard website. EPOX 8RDA motherboard users can be from ftp://ftp.unika.com.cn/support/motherboard/epox/
DRIVE / U2V2_1_2_1.exe Download the latest USB2.0 driver version 2.1. Run the downloaded executable: U2V2_1_2_1.exe, (Figure 3) restart your computer as required.
After restarting, the new hardware device will find the new hardware device: Standard Enhanced PCI to USB Host Controller and USB Root Hub, and automatically install the driver (Figure 4). After completion, there are five "universal serial bus controllers" (Figure 5) in the device manager.
2. Update USB2.0 driver
At this point, the USB 2.0 driver is not installed correctly, and the installed driver is notified. Open "Device Manager" to find "Standard Enhanced PCI to USB Host Controller" under the General Serial Bus Controller, right-click, select "Update Driver", Hardware Update Wizard, select "From the list or specified location Install (Advanced) "(Figure 6). Click Next, choose "Do not search, I want to choose the driver to install (Figure 7). Click" Next ". Select" NVIDIA USB 2.0 Enhanced Host Controller ", there is" this driver " After digital signing ", you don't need to manage it, click" Next "(Figure 8), start the update driver. Subsequently, the system will pop up and find the" USB2.0 root hub device "dialog box, you need to use the same Method Installing the driver. Open "Device Manager" will see the "Universal Serial Bus Controllers" device in the system device, including two USB2.0 controllers, USB in the General Serial Bus Controller The controller is also reduced to two (as shown in Figure 9).
At this point, insert USB 2.0 devices, such as USB2.0 flash drives, USB2.0 hard drive, etc., the system should correctly identify high-speed USB devices and can read and write normally. Insert USB1.1 equipment, such as keyboards, mice, etc. of the USB interface, and Windows XP has no response.
3. Fix the USB1.1 interface driver
Open "Device Manager", find the two "Standard OpenHCP USB Host Controller" under the General Serial Bus Controller, click the right mouse button to select "Uninstall", then click "Scan" in the right mouse menu Detecting hardware changes, the system will automatically update the USB1.1 controller driver. The USB controller has increased from the original two to four in the General Serial Bus Controller. At this point, inserting the USB1.1 low speed device system has been properly identified. (Note: If you do not uninstall two "Standard OpenHCP USB Host Controller" devices, "scan detection hardware changes", although four USB controllers will appear in the General Serial Bus Controller, but low-speed USB devices are still Not available). The USB2.0 driver is now installed correctly.
Finally, check whether the boot setting is set to "enable", and if you have the mobile hard disk setting, you want to set the mobile hard disk to "enable".
