This was installed in my Mac Pro and it worked immediately with no glitches whatever. Power down, unplug, open the side cover, and choose slot number 4 or 3. Remove the metal dust cover from the opening where your four USB ports will poke through the back panel. (This requires removing 2 screws). Gently slide the PCI express card into the expansion slot, making sure the metal tab slides into the same slot that held the metal dust cover you removed before. Reinstall the locking bar that has the 2 screws you undid before. Put the side cover back on and lock it. Plug in, power up, and you now have 4 more USB ports. There's no software to install, and if you're a Mac Pro user there should be no trouble at all.

The card worked out of the box in my Mac Pro. The package includes clear instructions for installing in various model Macs with PCIx slots, including recommendations for which slots to use as well as instructions for using the Expansion Slot Utility.app to set the slot configuration if needed (/System/Library/CoreServices/). Of course, I can't say anything about reliability as I've only had it installed a few hours; I'll update this review after a few months of use. The whole process of installing took about 15 minutes. (NOTE: the 5th port is internal so it's not very useful.)

I installed this card in my Mac Pro. It was quite easy to do. A card is better than external ports (for some you even need separate power). Works fine. Price was okay (for a PCI Express).

Card works fine until my Mac Pro 8-core goes to sleep. After that it seems impossible to restore USB connectivity. Sonnet claims the issue is that Apple broke/changed the USB driver since Mac OS X 10.6. Read their FAQ before purchasing!

The card works with no problems in a 2008 Mac Pro. Just open the case, install the card, and boot your machine back up -- done. Since finding 3rd party hardware for the Mac can be such a pain, it was nice that this worked out of the box, just as advertised.

The name of the 5 Port USB 2.0 Pcix Card mac/win is misleading. There are not 5 ports to the outside of the computer, just 4. I knew this when I bought them, so I wasn't disappointed. I bought 2 of these cards so I wouldn't have so many cables connected to hubs all over the place. They are installed in PCIe slots 2 and 4 and work just fine. I now have these 8 USB 2.0 ports as well as the 3 that came on the back of my Mac Pro computer. There is a place to plug everything in without using the ones on the front of the computer as permanent ports. I even have some empty USB ports for future accessories. I am very happy with them.

At this moment there are a handful of manufacturers that make a USB2 expansion card that is PCI Express compatible. I have a Vista x64-bit Operating System and I periodically run into issues with compatibility, but this Sonnet USB expansion card was an easy install, and it worked flawlessly. No issues at all. It took longer to find a screwdriver to remove the PC cover than it did to do the install.

To minimize current running through the card, I connected my PC power supply to the optional power connector and currently run 4 items off of the rear USB ports. I've had this expansion card installed for about a month and everything still works great. I would highly recommend this card to anyone that wants to add additional USB 2.0 ports to their computer with a PCI express card.

This card works flawlessly. No more USB under volt error messages or USB devices dropping out or loss of connection hiccups. Simple stated, this card works as described and I highly recommend it to anyone needing additional USB ports and has an open PCIe slot.
