Anyone knows how to remove a USB drive using the win32 API? I do a lot of work on embedded systems and on one of these I have to copy my programs on a usb-stick an insert it into the target hardware.
Since I mostly work on the console I don't like to use the mouse and click on the small task-bar icon hundret times a day.
I'd love to write a little program to do exactly that so I can put it into my makefiles, but I haven't found any API call that does the same thing.
Any ideas?
It looks like Sync lets you specify -e to eject removable drives. While not a win32 API, you could probably just call sync -e [drive_letter] from your makefile.
This article and sample should do the trick: http://support.microsoft.com/default.aspx?scid=kb;en-us;165721
You can use the CM_Request_Device_Eject() function as well as possibly some other possibilities. Consult the following projects and articles:

Here is a technet article about removable storage media. Look for DismountNtmsMedia.
Here's a solution in Delphi, that I've modified and put into a service for use in a very large enterprise. Go to: link text
Look for "scapi (Setup & Config Manager API)", and download it. There will be a demo program called USBView that will get you on your way. If you have Delphi, this also includes a TUSBDeviceTree component that you can use to gather information about a USB device when.
