We are updating a co-installer for our device. And we need to
disable the device and then enable it again, we use CM_Disable_Devnode/
CM_ENABLE_Devnode before, but MSDN said that "Do not use this
function. Use device installation functions instead". But I can't find
any function in SetupDi group that just disable a device and enable a
device. Could someone help me ? Thanks a lot!

look at the devcon sample to see how to enable/disable using the right APIs

Thanks for your reply. But I have another question.
I've looked at the devcon sample code already, seems that it
called SetupDiCallClassInstaller to issue DIF_PROPERTYCHANGE to enable
(disable) a device. From MSDN we know that "For each DIF request,
SetupDiCallClassInstaller calls any class co-installers registered for
the device's setup class, any device co-installers registered for the
specific device, and then the Class Installer supplied by the system
for the device's setup class, if there is one. " But I want to enable
(disable) a device in my co-installer, does SetupDiCallClassInstaller
() still can be used? Thanks!

SetupDiCallClassInstaller with proper code.

Look at DEVCON source.

During which DIF_code would you like to enable/disable the devnode? Why?
