Strange problem indeed.
Does the EDU09 software run in demo mode on this PC when the EDU09 is unplugged?
Yes it appears so.
Runs fine, and stays responsive.
With the EDU09 plugged in, if i opt out of the calibration it still gets unresponsive.
It might (read might) be because my machine is actually a VM running off of an unraid instance. meaning the USB layer is virtually passed from one machine to another.
It could be that while other USB devices functions okay, the EDU09 might not behave well in this configuration.
... I'll try doing a USB bus passthrough, which should eliminate the virtual layer altogether.
