Win7 x64 Eclipse Unrecognized phone/adb interface with yellow exclamation mark, unrecognized

The company is out of power today, so take the Android project back to the dorm. The notebook in the dorm is Win7 x64, the phone is connected to the computer, Windows can be identified, but Eclipse's DDMS is not recognized, nothing:

Then open Device Manager to view, found that Windows can identify the device (HUAWEI c8817e), and the ADB Interface (some machines may show Android ADB, etc.) but the yellow exclamation mark, is the driver is not installed properly:

So how to properly install the ADB interface driver? Toss a night plus a morning, still no way, what system32 directory, sysWOW64 directory, Winusb.sys and so on have tried, do not work.

But the company that machine on the 32-bit Win7 is able to install the normal driver.

Eat lunch sleepy state, continue to aimlessly Baidu, accidentally found an article, solved the problem:

The steps are as follows:

1. In Device Manager, locate the ADB Interface, right-click, and select "Update Driver software"

2. In the pop-up window, select the second item, which is "Browse the computer for driver software" (the problem of the driver has never been considered the second item, simply think that the driver must be found on the net rather than in Windows)

3. Continue to select the second item in the Pop-up window, "Select from the list of device drivers on your computer"

4. Leave the default selection in the pop-up window and click "Next"

5. Select "Install from Disk" in the pop-up window

In the Install from Disk dialog box, from the manufacturer file copy source, select the Android_winusb.inf file in the Android SDK directory on your computer, located in the%SDK directory%\extras\google\usb_driver directory.

The actual path I chose is:

E:\ Software \adt-bundle-windows-x86_64-20140321\adt-bundle-windows-x86_64-20140321\sdk\extras\google\usb_driver\ Android_winusb.inf

6. After selecting the Android_winusb.inf path and determining, in the popup dialog box, select the third item, "Android Composite ADB Interface", then click "Next"

7. The installation process may appear some warning message, ignore, choose to continue the installation

8. Installation Complete

In Device Manager, the original ADB Interface with the yellow exclamation mark disappeared.

In Eclipse's Ddms, an already connected Android phone can also be displayed correctly:

All right, problem solved! Now the 64-bit Win7 computer can also write an Android project!
