I know this is an older thread, and there might be a newer one for the issue, but I didn't see it, so gonna revive this one. I've had this issue for some time, but hadn't really needed to stay connected until now.
I have a floor, and 2 HX stomps. The stomps do not disconnect, but the floor has done this for several years even after updates.
I have 2 pcs. It happens on both of them, so doubtful that it's the computer's problem, and I can see it's happening to people with OSX as well.
It actually just disconnected while I was typing this. :|
Any recent movement on this? Now I'm actually attempting to use it for more than a few minutes on a project and, with it disconnecting it will be a no-go.
*NOTE: I have used many different power situations and USB cables. No hub.
