Unplug USB device

Hoping that someone can help a novice with unplugging a USB device
automatically using VBScript (or any other technique for that matter).

My issue is this:

I'm using a USB hard drive for replicating my backup data from a Win2003 SBS
machine. Whenever a plug the hard drive to the computer the replication
starts using robocopy.exe from Windows Resource Kit.

If I could manage to automatically unplug the USB hard drive when
replication is finished I got myself a fully automatic process. Equal
functionality to a tape solution but with so much more space capacity :D

You can accomplish this with a script:

dim bDone
bDone = false

set oQuerySink = wscript.createObject("wbemscripting.SWbemSink", "SINK_")
set NVS = createObject("WbemScripting.SWbemNamedValueSet")
set oContext = createObject("WbemScripting.SWbemNamedValueSet")

set svc = getObject("winmgmts:root\cimv2")
svc.Security_.AuthenticationLevel = 4

svc.ExecNotificationQueryAsync oQuerySink, "Select * From
win32_processStopTrace where processName = 'robocopy.exe'", "WQL", 0, NVS,
oContext

do while not bDone
wscript.sleep 1000
loop

set oContext = nothing
set NVS = nothing
set oQuerySink = nothing

sub SINK_OnObjectReady(obj, oContext)

wscript.echo obj.ProcessName

end sub

sub SINK_OnCompleted(hResult, oErr, oContext)
wscript.echo "OnCompleted for the query sink hr = 0x" & hex(hResult)
bDone = true
end sub

Please forgive my ignorance... where in the script is the USB device
unplugged?

Thanks for the sample code Scott. I've already written the functionality I
need for replication using robocopy.exe. All I need is the code to unplug
the USB device.

Thanks in advance - Jonas Sackerud

Sorry this is not possible via WMI currently, assuming that by Unplugged you
mean disabling the USB device. However if it was a share on another
computer you could delete the connection to that share.

Yes, by unpluuging I mean disabling the device. Too bad that WMI doesn't
support this. Is it not possible to interact with the application showing in
the systray that handles unplugging of USB devices then (the green fellow
with an arrow)?

It would be so smooth to get this working, plug in the USB harddrive and
replication starts - when finished the USB drive is disabled and ready to be
moved offsite.

I know what you are talking about but I am not the expert here. Anyone else
know where to go?

I am very interested in your request because I working in a project that in
some way is similar to yours, so please, may you let me know if you get any
solution or clue? I keep on investigating too so I will do the same if I
find anything interesting.

Thanks in advance
