Hi, sorry to hear about your issue. 
The USB drive should work with all of the USB A ports so this could be a hardware error with your unit. 
Could you try using the included Wi-Fi adapter in the top USB port and seeing if anything shows up on the network list when you go to Setup > Network? You could also try using a USB MIDI controller if you have one. It would also be good to know if the back panel USB ports are functioning correctly. 
If both the Wi-Fi adapter and USB drive don't work on the top USB port, you can contact support@eventide.com and refer them to this thread.  This will create a support ticket in our tracking system, and they will advise you further about RMA details.
