Although Windows 7 RC has a large number of hardware drivers, support for some older Plug and Play peripherals is limited.
The author tries to make an old-fashioned camera run in Windows 7. The camera is a 2004 cottage product (the brand is "not loose"), to download to the official for Windows 7 driver is obviously impossible. When the camera was inserted in Windows 7, it was not properly recognized by the system and Device Manager displayed a yellow exclamation point and could not find the driver. Although the video camera chip is 301P, the 301P chip's camera driver does not yet have a for Windows 7 version.
At this point, I thought of Windows 7 can update device drivers through Windows Update. So I decided to try my luck.
Click the "start → All Programs →windows update" command to open the Windows Update window and click the "Check for Updates" link in the window. Sure enough to find 2 important updates and 5 optional updates, click on the "2 important Updates" link, Vimicro-image-lenovo Q350 USB PC camera driver impressively. After selecting this update and installing it, the Lenovo Q350 USB PC camera icon appears under the Device Manager's image device. This shows that the author of the cottage camera has been successfully installed into Lenovo's similar camera, with QQ Video Call function test, all normal.
Through this practice, I found that Windows 7 's Windows Update Smart upgrade peripheral device-driven capability is still trustworthy. If there are some old devices that need to be installed to drive, try it in a similar way.
