That's crazy! It certainly sounds like the mouse has a high voltage short to the data line, and the ASRock board didn't have any built-in protection. [https://electronics.stackexchange.com/questions/161570/can-a-faulty-usb-device-fry-other-devices-on-the-same-hub|Here's a relevant discussion from an EE forum]: [quote]It is possible, particularly if the device is self-powered. Attempting to draw too much current or even a dead short will not hurt a proper USB host port. However, accidentally applying high voltage to either of the data lines could be bad. At least that could blow out the drivers for that port, but it's no stretch to imagine it could take out the whole hub chip.[/quote] Send that killer mouse to the recycler and post some photos of your board here.
