Before trying any of the following suggestions, what type of port are you connecting the hydra to? of it is usb 3.0, try a non usb 3 port and see what happens.
if the preceding suggestion did not help, here are a few things that you can try:
Try to reboot computer and see if that will help, perhaps the usb port on your pc has been corupted.
If you see that lego mindstorm thing, uninstall that driver by going into the properties of that device and then select to remove from pc completely. Reboot pc and then plug the hydra back in and it should re attempt to find the correct driver.
Uninstall the GHI SDK completely and then re install it. There may have been some kind of driver corruption and follow number 2 if you get the old driver showing up.
