good point!
tried all ways:
- connected by hub without power
- connected by hub with power
- connected by PCI Hub card (internal)
- connected by direct REAR usb slots
- connected by direct FRONT usb slots
For each connection I uninstalled and reinstalled the software
Spent lot of time for that but I got the same result
I recently decided to change my hardware in favor of the steinberg brand order to avoid these problems…grrr
