I have a Fireface UC and can't figure out how to access the setttings from the Firface itself.  I'm using Pro Tools and have always accessed the buffer sizes for the Fireface inside of Pro Tools.  Yesterday, I accidently adjusted the buffer size to 96 and when I shut down Pro Tools and restarted it, Pro Tools wouldn't open because it said that the buffer size I had in Fireface was not supported by Pro Tools.  The Catch 22 is I can only access the settings from Pro Tools and can't figure out how to adjust the settings from Fireface directly.  In the manual, it says click on the "fire" icon, but I've never had that or seen it.  The only icon I have is in relation to Total Mix and there's noting on that that will enable me to get into the Fireface UC settings pannel.  Somebody, please help me!
