Just for the info guys, my GS64, still won’t work after unplugging whilst my laptop is live, seems know body can understand why its happening but its the same on a mb pro 2015 and a newer MacBook, 2017 i believe, works when plugged from powered on, does not work when unplugged and replugged whilst laptops are are.
This is not a usb hub issue and most certainly not an issue with hardware.
My instinct is something with the serialOSC software. love to get this fixed or im afraid ill be selling my grid, as it hasn’t been used in months because of this
