How to delay loading of Windows Embedded CE driver

When developing Windows Embedded Ce (wince) and using Huawei 3G modem em 770w, we found that the driver was faulty and required delayed loading. Later I found a simple method to delay the loading of the driver.

Add the flags entry to the registry of the driver device. The value of this item is 4, indicating that the driver will not be loaded automatically.

Devflags_noload 0x00000004
-Allows you to have the registry settings, but not actually have the driver loaded.
You can useThisTo keep the driver from loading until you call ActivateDeviceEx () You can setThisFlag,
But you must clear it before calling ActivateDeviceEx ()

 

If you need this driverProgramCall ActivateDeviceEx () to load the driver.
