Yes, using SetupDi* functions.

Hello,

In Win2000 when I call "SetupDiRemoveDevice" it removes bluetooth
device from "Device Manager".
But it still works fine ( I have installed third party bluetooth
driver for Win2000).
And GUID_DEVCLASS_BLUETOOTH in "SetupDiGetClassDevs" doesn't works in
win2000.
So how can I find out installed bluetooth device in PC.

Thanx

If you remove the driver, the device will be left unattached, and Windows
will install the best driver for it at the next opportunity.

If you want to disable, as you first said, try something along these lines
(this is C++/CLI code, but the steps should be readily apparent, mostly you
want to replace the error handling):

void Device::Disable( void )

{

SP_PROPCHANGE_PARAMS params;

params.ClassInstallHeader.cbSize = sizeof (SP_CLASSINSTALL_HEADER);

params.ClassInstallHeader.InstallFunction = DIF_PROPERTYCHANGE;

params.Scope = DICS_FLAG_GLOBAL;

params.HwProfile = 0;

params.StateChange = DICS_DISABLE;

if (!SetupDiSetClassInstallParamsW((HDEVINFO)deviceSet,
(PSP_DEVINFO_DATA)deviceData, &params.ClassInstallHeader, sizeof params))

throw gcnew WinapiException();

if (!SetupDiCallClassInstaller(DIF_PROPERTYCHANGE, (HDEVINFO)deviceSet,
(PSP_DEVINFO_DATA)deviceData))

throw gcnew WinapiException();

}
