![]() ![]() Microsoft provides the general driver, and typically an independent hardware vendor provides the specific driver. The drivers that handle device-specific tasks go by a variety of names, including miniport driver, miniclass driver, and minidriver. In a driver pair, one driver handles general tasks that are common to a whole collection of devices, while the other driver handles tasks that are specific to an individual device. Driver pairs like (miniport, port) can make driver development easier.

INF file contents are the one which makes major difference. Hello, I could successfully install Virtual-Miniport Adapter. There are two ways to enumerate Virtual-Miniport adapter 1. All other Miniportxxx callbacks are just dummy functions without any content. The implementation has only DriverEntry and Unload routines populated. ![]() In Device-Manager (Control-Panel Interface), I can see Virtual-Adapter listed with a Warning mark ("! on yellow"). Iam getting error in installer wizard as " This device is not working properly because Windows cannot load the drivers required for this device" (Code 31). Though the registration with NDIS (NdisMRegisterMiniport) returns SUCCESS. Driverentry is getting called, but immediate after that Unload routine is getting called. ![]() I am trying to install it with "Add new Hardware Wizard". I have ported it to NDIS 6 and trying to install it on Windows 7, by using the same INF file provided with "NetVMini" Sample. Hello, I have been trying to develop a Virtual-Miniport Driver (WiFi) for NDIS 6.x on Windows 7. ![]()
