Hey! I write a driver for usb device.
I can call UpdateDriverForPlugAndPlayDevices to replace inbox driver with my
driver when device is on system.
But if device is not on system, I must delete HKLM/CurrentControlSet/
Enum/USB/{ID Value} to force device recgonize
when it replug on system.
In XP I can delete it, but how can I do it in Vista?
Thanks a lot!

Hello,

Your setup program must ask to be ran "as administrator" in order to perform
these functions. Otherwise, Windows Vista will run the program as a standard
user, which will not be able to change registry keys under HKLM.

Here is a very detailed document explaining how to do this:

Hi, wrong news group, but please refer to the "devcon" example in the DDK
for performing re-install of devices. Do not delete these keys... One time I
spent weeks debugging end-users issues because a driver installer writer of
a single unnamed product decided to modify the Enum keys directly! Search
for "Device Installs: The Good, the Bad and the Ugly" to find a WinHEC 2002
presentation on these issues.
