Velleman K8090 card

I have a Velleman K8090 card to control 8 relays channels.
While this card has been installed using Windows XP, it has functioned correctly. But recently I’ve changed to Windows 7 and it does not detect the USB port. I’ve already tested the USB port with another device and it works correctly.
Any support will be appreciated. As far as I know the drivers located in the Velleman website are compatible with Windows 7.

Thanks,
Santiago

This sounds like you did not download and install the drivers.
You can download them here.
