Oh man! I'm so stupid! I didn't even know Fireface USB was a software! Sorry for my dumbness! It all works now! RME RULES!
Don't worry :-) FYI .. There are usually two files:
1) Firmware update tool, fut_......
2b) TotalMix FX software, the DSP mixer(last stable version bundled together with the driver)
Occasionally, RME releases new functionality on this forum
- either new TotalMix FX software or
- new driver / features which might also need a firmware upgrade
The instructions and requirements you will find in the forum post
The driver settings (Windows: the little icon in the notification area at the bottom right of the Windows taskbar)
are for configuring some low-level stuff in the driver, related to digital I/O ports or WDM devices for Windows and some more stuff.
There is also additional stuff available for download: DIGIcheck, TotalMix Remote (only to be installed on a remote PC which has no RME interface installed) and a few other.
