The role of Windows Mobile bus driver cannot be underestimated

The driver of Windows Mobile is actually a tree structure. Device.exe is responsible for loading almost all drivers, and various driver information exists in the registry. In the system startup stage, device.exe does not know how many drivers need to be loaded. He just finds the bus driver, and then it continues to load all the drivers, so the bus driver is a very important driver and is a bridge driver.

In the Registry, the key value rootkey of HKEY_LOCAL_MACHINE/drivers indicates the location of the bus driver. Generally, you will see drivers/builtin. The DLL in HKEY_LOCAL_MACHINE/Drivers/builtin indicates the name of the bus driver.

By default, the accesskey of Microsoft has a drive busenum. dll (the source code is available in public ). This driver will enumerate all the key values under builtinand route these drivers to device.exe.

Bus driver OEMs can be replaced. At this time, you may recall that since there is already a ready-made product, why do you need to write it yourself?
