Wondering if a fix was found for this, as I am having similar issues: Addressable lights work anywhere from 30s to 3 minutes. At that point, the LEDs either freeze with what ever trigger was hit, or if none the LEDs remain black. I have to stop DOF.exe, reset the USB connection, and restart DOF.exe. I know DOF is working and continues to work, because all the other toys continue to work, after LEDs stop working. DOF indicates 0 errors, as it is working fine. I have tried different, USB ports, USB cables, purchased new USB PCI board to try different ports, as well as checked the USB not to suspend - all yield in same issue. I am wondering if it is the Actual Teensy board having an issue. Anyone else experience something similar or currently experiencing the same?
