What is the problem?
Unable to connect to my Creality CR-10 via USB
What did you already try to solve it?
Quite a bit. Checked dmesg output for hints as to what might be going wrong. Checked /dev/tty* for any devices I might be able to add to Octoprint to get it to connect. Also checked lsusb output, and can see what appears to be the printer listed. Manually set baud rate in Octoprint to 115200 as directed in many postings, but still no success.

So, I have done lots of research on this, and genuinely can't find the issue. Listing of /dev/tty* gives the following:

Tried adding ttyAMA0 and ttyprintk to the list of additional ports.
output of lsusb is as follows:

I believe device 009 is the printer, so it's being picked up by the OS.
I expected to see /dev/ttyUSB0 listed, but it's not there at all, so obviously adding that into the list of additional ports is a waste of time.
Anyone got any ideas? Would really love to get Octopi up and running.
Thanks
