Have you done the USB troubleshooting steps I gave you? Did you remove the Virus Synthesizer during those steps as recommended within the steps?
You have not provided us with much information as to what steps you have taken so far. If you have done the USB troubleshooting with the Virus Synthesizer removed, then you should remove it completely for a time and see if crashes continue. If they do not, then contact the manufacturer of the Virus Synthesizer device.
