3/26/2014
The following registry key example shows the settings for the sample HID driver.
[HKEY_LOCAL_MACHINE\Drivers\USB\LoadClients\Default\Default\3\Generic_Sample_Hid_Class_Driver]
"DLL"="USBHID.dll"
This example shows that the driver in Usbhid.dll is called Generic_Sample_Hid_Class_Driver and is loaded for any interface with an InterfaceClassCode of 3.
According to the precedence rules for loading USB device drivers, if the settings for the mouse and the HID drivers are included in the registry, the HID driver is loaded first because it has the more general Group3_ID subkey.
