Eject ? On a USB ?, you mean safely remove, dunno but you may want to disable it
( same effect as safe remove, flushes all buffers to disk ).You can use DevCon, available from
http://www.ed-dyreen.com/eDOS%20beta%20 ... 7.11.2011/Find the device for your class which is 'USB: USB-controllers' and disable the device.
something like:
Code: Select all
@echo off
DevCon.EXE /?
DevCon.EXE classes
DevCon.EXE help FindAll
pause
exit 0
Code: Select all
for %%! in ( "USB"
) do (
for /f "tokens=1* delims=: " %%A in ( 'DevCon.EXE FindAll ^=%%~! ^|findstr /i /c:":"'
) do (
set "ID=%%A"
set "DEVICE=%%B"
set "HWID=!ID:~0,21!"
)
)
"DevCon.EXE" disable !HWID!
