On every device I've ever used with the squared USB port, the end of the cable clicks into place. That includes the HX Effects I have. The cables lock into the jack, no problem . On the Helix, the plug end just barely stays in, dangling downward. It is visibly larger than the one on the HX Effects. I found a Mickey Mouse solution, however. I cut a thin piece of electrical tape, wrapped it around the jack itself, which then fit more secureley into port/socket . Once I did that, I plugged the other end into a USB hub, which Line 6 apparently does not recommend. Worked like a charm. HX Edit now sees my unit and I can do all the functions on the computer.
