Hi Jonathon,
Any other system updates take place?
If it's not working with multiple computers, that would be more likely to point to a hardware failure. If it's not showing in the USB section of the System Information report, and you can't get it to update the firmware (even to the same version), then please contact a Pioneer DJ authorized service centre in your region to have your hardware inspected and/or repaired.
