The Firewire ports on my 2012 Mac Pro 5,1 (with Metal graphics card running Mojave) are beginning to flake out, as they tend to do. Some work reliably, some don't work at all, some intermittently. I was advised that what usually goes bad is the Firewire controller, and a way to deal with it is using a FW PCIe card. I tried the Sonnet Tango FW/USB2 card; Apple System Report saw it, but I couldn't mount any drives.
I am thinking of buying a new-in-box Sonnet F8USB3-E, as I also need the USB 3.0 ports (I am currently using a Sonnet USB 3.0 card in that slot successfully). Are there any caveats with getting this card to work? Does it need a particular slot? There is a 12v internal molex connector (so the card can drive bus-powered drives); does that need to be connected? It should be plug-and-play, but the USB 2.0 version of this card. wasn't.
