I bought this from someone who purchases used audio equipment in bulk. He will refund my money if I cannot get it to work. He did not know anything about it. It will not boot. The power turns on and the green LED's next to the System and Audio buttons flash for a second and then the LCD displays "becoming EZbus... It does not advance from there. When connected to a PC computer via USB, the computer recognizes that a USB device is found but cannot install it because it does not recognize what it is. I went to the Event support site and downloaded the EZbusInstaller, Firmware, ASIO update and XP update. Followed instructions to install the Installer and that seemed to work, but when I try to run the Firmware it does not recognize the unit and gets and error message that says no EZbus connected. The Firmware instructions say that in order to run the file, the unit has to be set so that the display is at the USB setting, by pressing the System button and then the Next button several times. But it won't pass the message that shows "becoming EZbus..." Can anyone help? Is this a hardware or software problem? If software, is there a workaround to get it reset? Thanks, RK
