If you are upgrading to Pro Tools 9 on either Mac OS X 10.6 or Windows 7, it is important that you install the latest device drivers separately from the Pro Tools 9 installation. In Pro Tools 9.0 and higher, the drivers for most devices are not part of the Pro Tools installation.

The Pro Tools Software Installation Guide Version 9.0 document recommends installing the latest device drivers before installing Pro Tools 9:

However, if you are installing or updating to Pro Tools 9.0.1 or higher, Avid recommends installing the latest device drivers after installing Pro Tools 9.0.1 or higher. See Also:
