The following post is for SMART Board users who cannot get their Macintosh running Parallels software to recognize the SMART Board in Windows OS. In my situation, I was able to get the SMART Board recognized while running Mac OS. However, when I switched to Windows XP using Parallels software on my MacBook Pro, Windows would not see that I had a SMART Board connected. I would go to the SMART Control Panel and the SMART Board Settings link would not see that I had connected it using the USB cable. If you have suffered through the same situation, try the following steps which I found successful on my Mac.
Launch Windows OS.
Next you need to remove Parallels Tools if present. To do this, go to the Control Panels in Windows and select Add/Remove programs. Select Parallel Tools and click on Remove.
After it finishes the removal, go to the Start menu in Windows and Turn Off Computer (it will only quit Windows.) Next quit Parallels software.
After you return to Mac OS, start up Windows again. From the Parallels menus, click on the Actions menu and select Install Parallels Tools.
After Parallels completes the installation, Turn Off Computer from within Windows and quit Parallels.
After you return to Mac OS, start up Parallels (not Windows) from the Applications menu.
Go to the Edit Menu and select Virtual Machine. On the left side of the new window, select the USB controller from the list of resources. On the right side of the window, under device status make sure Enabled is checked. Also under Connection Options, select Connect to Guest OS.
From the Action menu, start up Windows OS. After Windows is running, connect the USB cable from the SMART Board to the Mac. If the device doesn't appear automatically, you should go to Devices menu and select USB and choose it from the list.
