How to uninstall a device from user mode application

NTDEV
1

Hi,
I have few questions on setupDi functions and installing and uninstalling
devices.

  1. How do I uninstall a device from system?
  2. How do I rescan ( scan for hardware changes)?
    Both these functionalites are available from DeviceManager. Is
    CM_Reenumerate_DevNode sufficient to update system? Sometimes I have
    encountered that SURPRISE_REMOVAL PNP message comes aftet short interval.I
    am aslo calling IOCTL_SCSI_RESCAN_BUS and IOCTL_STORAGE_FIND_NEW_DEVICES to
    handle legacy devices. Is it required?

any help is appreciated.

thanks

check the following samples in XP DDK :

\src\setup\devcon - for reenumerating devices
\src\setup\remove - for removing devices
\src\setup\install - for installing devices
