it is the arduino. it disappears when I unplug it and reappears when plugged back in. I have tried two different USB cables. I also tried a different uno and it came up the same. I am guessing this has to do with the ubw driver
I installed .91 and I am back to where I was when I upgraded to .92. I can see the arduino uno in device manager – USB-SERIAL CH340 (COM3) but when I try to connect using the eggbot extension in inkscape I get “Failed to connect to EggBot. :(“
