New SimuCube build doesn't to connect to Ioni

We tried to find what the issue is with Sebsimracer’s Simucube. Sadly, neither the X3 nor the X4 USB port have any activity to the PC, so the suspection is that some type of a electrical issue has happened to the Simucube.

Thanx for reply, Mika, anyways, this is a good informative thread, can it be pinned, please?
