after a really long break (my former ID is cancelled meanwhile) I just like to post that I finally got it running....
For years I kept an PC with Windows XP 32 bit to keep Cubase 4 working together with the DM24 via the IF-FW DM. With Windows 7 / 8 or 10 I got the fw connection running but in Cubase there were no ports/channels visble because of a ASIO / WDM driver problem.
I refused to buy a new mixer just because of not having "windows signed drivers"......
With Windows in test mode and a tool (instead of a DOS command line) to sign drivers I got the original tascam drivers working.
Cubase 7.5 32 bit: 24 ch in + out, without further workarounds
Cubase 7.5 64 bit: you have to activate "WDM on all channels" via the IFFW DM driver tool
with XP and Cubase 4 I had drop outs, system hangs etc etc
now it´s very stable
