From: Echo on 10 Jan 2007 20:55 Disable is just disable like what Device Manager does, not ejecting device from system.

From: Echo on 11 Jan 2007 03:41 Sorry, I can't get yout idea. What I mean in last post is, Both Remove and Disable utility of devcon can't eject removable devices from system. Removable devices (not only use devices) surely can be disable, eject and uninstall. Other replies to this post have given solutions to eject these devices.

What I meant to ask is what kind of USB device can be ejected, I just don't know such. Give me example?
