Disconnect the hardware and uninstall it, restart your system and try again.
Don't forget, some hardware has to be connection before the installation, some during the installation and some after the installation. Look for it ad the manual.
What you could try to is, uninstall the software, restart and install again.
Try to download the software (again?) from the firms website, there you can look ad there FAQ's and ask them for support.
Is it the latest, try the one before (CD?).
Hopefully I let you know enough and that you will find the answers you seek!
