Hello,

I've been using a Firestudio Project interface for more than a year now with my ASUS Republic of Gamers laptop. It took some work to get it running, and a couple of dongles to go from firewire to Thunderbolt 3, but it was doing fine. I then bought a second FSP on eBay so I could add more inputs. But when I first connected it to the computer it wouldn't sync. The light glowed a steady red. I tried using Device Manager to get the computer to update to the right drivers, but that didn't work. I tried uninstalling and reinstalling the latest version of UC and that didn't work either. My original unit would work fine, but not the new one. I even tried uninstalling the latest version of UC and then loading the version that came on the disk with my original FSP, which is how I got that one to work when I bought the new laptop. I contacted tech support, but all they've really done is point me to the articles and procedures I'd already found on the Knowledge Base. Their last suggestion was to install a Firewire card, which really isn't practical in my laptop. Now, after all of this, my laptop doesn't recognize my original FSP either. Instead of seeing it as an audio input it seems to be seeing it as a sound card. That's what was happening with the unit I purchased on eBay too. Any suggestions on how I can get the proper drivers connected to the FSP so I can get the comforting blue light?

Please help

I didn't find the right solution from the internet.
