Pro Tools 5.1 hangs with tapping fingers when selecting the port in the setups > peripherals dialog when attempting to configure the USD.

This can be caused by a corrupted OMS setup. With Pro Tools quit, go to the system folder > oms folder > oms preferences. Trash the OMS Current State file and empty the trash. Reboot Pro Tools and when it prompts you to reconfigure OMS either hit cancel to bypass or hit okay to make a new OMS setup.
