Works fine as all my Adaptec purchases do.Helps extend the lives of my older systems.
However, you will only get the USB 1.1 speed as noted at the Adaptec website. Great if you need more ports but not faster speed. I have the AUA 3020A which is different from the picture. The Mac hardwired Firewire is considerable faster than the PCI based Firewire. I rated this a 2 star because the label is somewhat misleading for Mac users looking for USB 2.0. There's 1 firewire, 3 USB and a smaller square USB port. I bought this to upgrade to the faster USB 2.0 for my Mac Quicksilver 2002.
Sorry for my poor english. I can say This company can be update to the newest operating system. I've mounted on my old PC with a new Windows Vista and I can say it's wonderful that this card can be auto-recognized without drivers when Windos Vista runs. I've read all about this cards, and Adaptec cards did it.
All connected devices communicate stably, quickly, and reliably, freeing up my front-panel USB ports for other devices such as digital cameras and flash drives.If you need additional USB or FireWire ports, this Adaptec device is the answer. With its own power connector, this card allows a practically unlimited number of USB/FireWire devices to be connected to a computer.I've connected a printer, a scanner, and two external hard drives to this device and download digital camcorder DV via FireWire. Computer folks love to talk about the latest, greatest hard drives, flat-panel monitors, video cards and the like. Little mention is made of basic utilitarian components such as this.That said, the Adaptec DuoConnect AUA-3020 provides solid performance and system expansion and does it well, while calling no particular attention to itself.
