USB网卡可能无法在Win7下正常工作

Win7之家（ www.win7china.com）：USB网卡可能无法在Win7下正常工作

 据微软称，基于Vista驱动的USB网卡适配器无法在Windows 7 pre-beta下正常工作。该症状涉及到NDIS5.xUSB网络适配器无法在Windows 7性能监视器中正常显示的问题。NDIS指的是Network Driver Interface Specification网卡驱动界面标准，从XP到Vista，NDIS也从5.0版本升级到了6.0版本。

“性能监视器只会显示指向硬件连接器的适配器。在Vista和Server 2008中，微软引进了NDIS6.0这项全新的标准。现在网卡驱动开发者们都在努力开发基于这项标准的驱动。”

雷德蒙软件巨头并没有发布任何补丁以解决此问题，也没有任何迹象表明微软想要解决此问题。在Windows 7完成前，微软只是建议用户将网卡和驱动升级到NDIS6.0以解决此问题。同时，他们还解释称除非网卡都通过NDIS微型端口与系统连接，否则Windows 7都无法识别此类设备。

According to Microsoft, pre-Beta development milestones of Windows 7 fail to play nice with USB network adapters that rely on pre-Windows Vista drivers. The symptoms involve NDIS 5.x USB network adapters not being displayed in the Windows 7 Performance Monitor. NDIS refers to the Network Driver Interface Specification library, which, following the transition from Windows XP to Windows Vista, evolved to version 6.0. Version 5 of NDIS was used by Windows operating systems before Vista.

“Perfmon only shows adapters that indicate that they have a physical, hardware connector. Windows Vista and Windows Server 2008 introduced a new Network Driver Interface Specification (NDIS) known as NDIS version 6. Network driver developers are encouraged to move their drivers to this new specification,” Microsoft revealed.
