Not happy! My Audiobox 1818 suddenly stopped working. I have it plugged into a USB 2.0, everything was fine for the last 6 months, but then it stopped working all together. I think it's having a firmware issue, but now it wont sync up to any of my computers at home. I've tried three of them, installing new universal controller, but it's just red lighting, and doing the christmas tree light show...I've had nothing but problems with this crappy device since I've owned it, and it only gave me about 6 months hassle free. Yes my sound settings are 48,000, yes I have installed, uninstalled, reinstalled, turned off, waited the stupid 15 minutes...everything...This is the worse sound device ever made. Presonus should be ashamed. I have a backup 22vsl which doesn't give me any problems...but the 1818 is ***** across the board. No one is happy with it. So many problems in so many forums. What can I do besides take a sledge hammer to it and NEVER purchase another product from presonus again!!! *****!!!
