With just buying some usb2 controllers instead of the usb3 ones, seemed to = have "fixed" my problems for the time being. :-) There were also some more problems with XHCI, so it just hasn't matured eno= ugh. It's only a pity (E/U/O)hci controllers under linux don't support MSI inter= rupts, Greg KH seems to have reject a patch for that. But apart from that it works fine !
