Hello!
Can I use the DDK call UpgradeDriverForPlugAndPlayDevices() be called
from an user mode application.
I tried this and it seems to pose no problem in 2000/ME/XP. But is this
right?
Does it have support on 95/98 also?
Any response will be helpful
Regards
Sriram

UpdateDriverForPlugAndPlayDevices is a user level call, it just happens to be documented in the DDK because it pertains to driver / device installation.

Hello,

Yes, only from a user mode application. This function is in newdev.dll
(newdev.h) and onyl supported for Windows 2000/XP/ME. Use dynamic
linking when you will write binaries for all systems.
Does it have support on 95/98 also?
No, installation is different. 
In this moment I try to use the function “SetupDiCreateDeviceInfo”
(see the message from jayadev), but it is not 100 % successfully.
