How to unload a driver ?

Hi,

Is there a way to unload a loaded driver without reboot?
I used ActivateDeviceEx and DeactivateDevice to disable
the dirver, however the driver still can be found using
FindFirstFileEx and FindNextFile and be opended
correctly.

I'm not sure, but it's possible that DeactivateDevice do not unload the
driver if it's still used by an application. Can you confirm you don't have
an active connection (i.e createfile call with no closehandle call) between
your driver and an application ?

If you called ActivateDevice to load the driver you should be able to call
DeactivateDevice to unload it. What is the return value you get from
Deactivatedevice? What does the debug output show?
