I'm trying to develope a program to safely eject an USB device. I have tried a lot of way but there was no satisfactory result. I used to consult wraithdu's script here : but that script wasn't work on my Win7 machine, then I heard someone talk about Devcon, then I started to explore it, I have scripted, tested for days and get nothing but errors. I used this command : devcon remove @usb\* to remove all removable devices but here the result goes :
All failed? I have just plugged on two USB Kingmax and Transcend!
I need some professional guys to solve the problem:D Thanks!
