Parallels and USB devices

One problem I have with Windows XP installed under Parallels on my Macbook occurs when I plug in new USB devices. You get prompted to connect them to the Mac or the virtual machine. If I select the VM then nothing further happens, windows sits there ignoring the device. I have to run a “_scan for hardware changes_” from the device management console to get it to pick up the USB device. It’s annoying since the command is buried under half a dozen clicks. So I was after a way of doing a scan programmatically.

After a bit of rummaging around I found the MS do a package called DevCon, you can download it here: http://support.microsoft.com/default.aspx?scid=http://support.microsoft.com:80/support/kb/articles/q311/2/72.
