Question

I have RML16Ai and Cs18Ai with Presonus Studioone 4.5. At Startup Studioone 4.5 notifies for not able to record. In the audio Setup i am unable to choose Presonus firestudio (The Audio Device Presonus Firestudio has failed to start correctly before. Do you want to try again). Even trying for multiple attempts it keeps failing. 

My Setup:

1. Windows 7 Ultimate/ Windows 10 (Tried on both OS 64bit Versions)

2. Studiolive cs 18Ai (Control Surface)

3. Studiolive RML 16Ai

4. Presonus AVB Switch 

Issue:

Unable to connect Connect RML16AI with Studioone 4,5 Software.

Control Surface 321.576.77 has no issue connecting to both the CS and RMl16i

OHCI info

Studioone 4.5 Error.

Please need your Support guys.

I tried both Windows 7 ultimate 64 bit and Windows 10 64 Bit Versions. Still the issue remains the same. Even opened Support Ticket with Presonus however the issue remains intact and unsolved.

Answer 1

FireWire is not a plug and play technology.

Hot plugging the cable with the computer and/or the mixer on can damage the 1394 connection.

First thing to do is to replace the cable. That should solve your issue.

If not, replace the firewire connection on your computer. You'll see that it says (Legacy) in your device manager.

This indicates Windows is using a 1394 device driver for the card in your computer is not current.

Update the FireWire card to a newer PCI-e card and your issue should be resolved.
