Sonnet USB 3.0/FireWire 800 Combo PCI Express Card

The usual Sonnet-quality product. Provides 3 Firewire 800 and 4 USB 3.0 (2 from board bracket, 2 from accessory USB 3.0 bracket or computer case front panel USB 3.0 connectors). The photo is incorrect in that it shows a board with no external power connector but the actual board does have the required 4 pin Molex power connector. The board has a Fresco Logic FL1100-1Q0 integrated circuit for the USB3 interface and an LSI L-FW643E2-F39G integrated circuit for the Firewire interface. Interface to the PCIe bus is handled by a Pericon Semi PI7C9X2G 304SLAFDE PCIe Gen 2 integrated circuit to interface with the motherboard's PCIe bus for a pure PCIe connection, unlike TI chipset-based boards which use a PCI-to-PCIe bridge chip to interface to the motherboard's PCIe bus.This board works in hackintoshes with no additional kexts (tested in OS X 10.8.x), except Gigabyte Z77X-UD5H motherboards, which appear to have a BIOS issue that prevents all boards with the LSI/Agere Firewire integrated circuit from working properly.Expensive, but works very well and provides both Firewire 800 and USB3.0 interfaces in one PCIe board.

On a 2013 Mac Pro Tower, Mountain Lion Mac OSX. Get this instead, 1/2 the price, no return issues and worked without a hiccup: The Inateck 4 Ports PCI-E to USB 3.0 Expansion Card for Mac Pro. I got this after and was a great solution. When I received it, I installed the card and restarted with drives connected. My striped 4TB RAID drive came up with the message "Initialize this device, unreadable by this Mac" instead of mounting and I was using it minutes before, working flawlessly. Unfixable, destroy the remaining data by reformatting or start restoring files. I had to get special RAID restore software and started that 2 week process.The USB 3.0 read/write was under standard for speed with the correct cables, when benchmarked it came up at about 75%, of average for 3.0 and yes, I know about Mac and USB 3.0 dropping to slower speeds. The Firewire didn't work at all until after weeks of trying drivers, etc. When I finally got the Firewire to see the drives, data transfer averaged at about 50% of FW 800. On boot the screen would flash brightly before starting up with this card in the PCIe slot.Anyway, $100 for the card, $100 for the RAID drive rescue and restore software, a 15-25% restocking fee... I'm guessing $25, about 25 hours of work (priceless time) restoring my system and about $5.00 postage to return it. This thing cost me $230 to try it since I haven't gotten my money back yet either. That's the absolute worst thing: I have had this card returned for a week or two and I still can't seem to get them to process the return! Where's my money? Way below my average Amazon experience. Not worthy of the association with them.

Still working, years later.

I originally bought this to add Firewire/IEEE1394 capability to an ASUS/Cooler Master tower I built in 2013 running Win 7 (now Win 10).Lately Firewire is no longer needed (it's obsolete anyway) and I observed when updating a Mac Pro with a set of USB 3.0 ports, the interface was similar (PCIe 2.0) and so popped it into the 2008 Mac ProNow it has two more USB 3.0 ports, and I don't need the power adapter. The Pro was notorious for a lack of USB

Given that my hackintosh had only one free PCIe slot, I was looking for the impossible. And here it came! The first one I ordered from a dodgy outfit came all wrong, namely as a Tango 2. Be careful, these Tango 3s are in short supply.I then ordered directly from the maker. Plugged it into my MSI motherboard with its i5 CPU running OsX 10.8.4, and that was it. It just worked. I got a panel mount dual USB 3.0 bracket to plug into the blue header on the card. I also got some 9 pin/6 pin Firewire cables, and one 9 pin/4 pin for my camcorder.On one card you thus get 3 Firewire 800 ports, 2 USB 3.0 ports, and another 2 on the bracket you connect to the blue header. I haven't had any events, or panics, or anything. It just works. Not surprising, given the top notch new chips they used for maximum compatibility.
