If I was to guess I'd say you hit a device detection bug in caiman. In
99% cases it can be easily worked around (providing you use 5.10
release) by enforcing the device node name in the cayman configuration
line.

So, click "Capture options" button (the cogwheel like icon, the middle
one of three) and make sure that the "Energy Capture" input contains

<DS-5-path>/bin/caiman -d /dev/ttyACM0

I have 5.10 (build 1389)
I tried putting this in the energy capture field:
/usr/local/DS-5/bin/caiman -d /dev/ttyACM0
(I also see /usr/local/DS-5/sw/energy_probe/caiman, but the one in /usr/local/DS-5/bin seems to be the script that sets things up for it and calls the latter)

I tried this, but still not getting anything. The only things I see in the timeline after running the capture are:
Linux Scheduler
Instruction
Disk IO
Memory
Network

Also, fwiw, I tried running caiman from the command line, even with specifying -d /dev/ttyACM0 and I get no output. Not sure if I'm supposed to get anything though. All it does is create an empty file called "0000000000"
