Hi All,

My Audiobox 1818 was working fine, before the update. Once updated to v1.49, the system is unable to detect the 1818...... the USB sync button will go from Blue to Red and blink between then stops at red. Is there any ways I can revert the firmware and stop the system from automatically updating the firmware? HELPPPP thanks

Just wanted to ask if you (or anyone having a similar problem) managed to fix it?
My 1818VSL was working great for around 4-5 years. My first firmware update to 1.48 ended in a failure since my USB cable somehow stopped working. The thing went crazy after that. I finally managed to update it succesfully to 1.49 (had to do a full uninstall from the Presonus page) and now I have the same problem. It goes from blue to red and my PC won't even recognize it anymore...

Any suggestions?

Thanks in advice,
Karol M.

Nevermind... I switched it off, waited a few minutes and it's working again. But it seems the firmware update to 1.49 failed. I'm stuck with 1.48. Still not sure if I can finally record anything or not.

Edit 2:
Allright... still nothing. After changing the bitrate to 16 bit, 48 kHz the device gets disconnected and I have to switch it off for a few minutes before I can use it again. Still not fully functional.
