I agree 100% with the last reviewer. The product will install and show up in your systems manager, but will not interface with anything. I tried my printer, a camera, 2 nights messing with it, looking for updates even called their support line, same thing as the last reviewer, "Wait for the next representative". Yeah theyre probably all working out in the shipping area, getting returns. Waste of money and time. Nothing works with it. Dont waste yours.Update to my earlier post. Just today I sent the product back and bought the Belkin 3 Port, 2 external, 1 internal USB. Its available from Amazon, seller is Office Depot. Awesome, very precise and easy to follow instructions. Installed the drivers, plugged in the card and BOOM I was in business. Best $29.00 Ive spent on a USB card. Taught me a valuable lesson. Buying cheap, always ends up being expensive. Its totally compatible and tested to work on Windows98 98se Me, Macs and XP.
