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
