Hey Guys,
I wanted to chime in and say I am also having this problem on the current version of windows 10 and Helix Edit. I can not really pinpoint what is causing the issue. I tend to play for a few hours at a time. Some days it does not ever disconnect. Some days it will disconnect a few times in a row, then go two hours without disconnecting.
I do not think it is related to power settings. I use a laptop and microsoft will adjust power settings based on if the laptop is plugged in to a charger (by default). The logical conclusion would be that I would be more prone to disconnected messages while my laptop is not plugged into a charger. This is not the case. I have only ever experienced the issue while my laptop is plugged into a charger. This would be an anecdotal observation/confirmation bias, but it would appear power settings/usb port powering down to conserve power is not the cause of issue.
I can say that I have experienced the issue on two different windows 10 laptops. I have used multiple USB cables.
