I am starting to get my head wrapped around Astroberry and Ekos, and I have nearly everything figured out except this issue. I use a Canon 60D DSLR as my main imaging camera, and I have a wired battery to keep the camera running constantly. I can get the camera to be recognized and connect to it in Ekos (the camera make and model are recognized, and it doesn't throw an error when I hit Connect) but when I go to run an exposure sequence, I get a "Failed to connect to serial port /dev/ttyUSB0" error. What is more bewildering to me is that I can use the live view button and get an accurate live view from the camera. I have tried Force Bulb mode on as well as using Bulb mode on the camera itself. I've also tried different USB connection cables. I have also run lsusb from the terminal and I can see a Canon device connected, but at times it can cut out if the camera goes to sleep.

I've looked at the instructions from someone named Jasem about updating the udev file, but I am not very versed in Linux and when I open the /dev folder I don't find any ports with USB in the name at all. Some of the other steps in the process fail for me as well.

Is there anyone else who has had this issue? I really want to make computer-controlled exposures work and get away from my intervalometer. Thanks in advance.
