From: Echo on 10 Jan 2007 01:19 Hi, Arkady Frenkel, I tried devcon, but the result is not as I expected. Remove utility of devcon will uninstall the device, instead of ejecting device only. And the source code uses SetupDiCallClassInstaller(DIF_REMOVE,Devs,DevInfo) to realize this utility, which causes the uninstallation.

If you're looking for a program which will force a device to be unmounted, look for a program called DevEject. -- - Gary Chanson (Windows SDK MVP) - Abolish Public Schools
