If the LED lights are the Pan LED’s, then your Qu has corrupted firmware and is in a firmware update mode (which would make sense if the update was not completed correctly).
You will need to format a USB drive to FAT32, then place the unzipped firmware in the root of the drive, as you would when carrying out a normal update. Insert the drive in the Qu, power it on and the update will happen automatically.
As you mention problems with the USB drive, you might need to use a different one.
If you’re still having issues, you can contact us directly through support.allen-heath.com
Thanks,
