I have just started having the same problem, out of the blue. Hadn’t plugged my Helix Floor into my computer for several weeks and now this keeps happening. But not with my Stomp XL, just the Floor. Did you ever get any resolve on yours?
I’ve redone my HX Edit and Helix drovers, checked for windows updates, reset and restored my Helix like 3-4 times now, at a loss.
