Unable to connect tau to microsoft windows

Hi everyone,

Quick question: What is dpinst.exe? I don’t have the stick anymore unfortunately. Is it the same as the Windows driver that can be downloaded online?

Background:

I’m trying to follow some of the instructions here to try and set up my Eigenharp Tau on Windows. I previously had it running semi-successfully on Mac (some instruments working).

I have the same problem on two separate Windows 10 machines: After installing drivers, runtime and resource pack, the Eigenharp only shows up as PSU-MM in the device manager, despite reinstalling the driver repeatedly, replugging cables, etc… On one of the two machines it briefly worked (showed up correctly in the device manager as an Eigenharp device, played synth sounds), but then when I plugged it in again later, it showed up as PSU-MM and nothing worked (same USB port, same everything).

Any advice is welcome. Also I’m trying to sell the device, any ideas whether this could be a hardware issue? It looks a lot like a software issue, but now that I have the exact same problem on two separate Windows 10 devices, I’m wondering whether it could be the case that the hardware is broken.
