How to programmatically unplug & replug an arbitrary USB device?

Question

I\'m trying to fix a non-responsive USB device that\'s masquerading as a virtual COM port. Manual replugging works, but there may be up to 12 of these units. Is there an API

Answer 1

I had to do this for my car computer project a while back. The touchscreen drivers didn't like going into hibernate and needed to be replugged when the computer came back from hibernate. The way I ended up solving it was to use Devcon.exe like DigitalRacer suggested. The trick however, was that remove/rescan on the controller didn't work. I had to do the remove/rescan on a HUB upstream from the device (which subsequently disconnected all attached devices).
