Access to USB port not working from PlatformIO - but working in Arduino IDE and in terminal

Just installed the PlatformIO Atom plugin, and can’t get access to the USB working.

In terminal prior to launching Atom:

/etc/udev/rules.d $ groups
jpeterse adm dialout cdrom sudo dip plugdev lpadmin sambashare
/etc/udev/rules.d $ ls -alh /dev/ttyUSB0
crw-rw-rw- 1 root dialout 188, 0 Jul  8 22:28 /dev/ttyUSB0
/etc/udev/rules.d $ ls -alh 99-platformio-udev.rules 
-rw-r--r-- 1 root root 9.2K Jul  4 02:44 99-platformio-udev.rules

Then in Atom, the PlatformIO device list is empty.

pio device list
sh-4.3$ pio device list


in the terminal in Atom:

sh-4.3$ groups
jpeterse nfsnobody

I have checked for updates to Atom and PlatformIO, and appear to be on the latest release.

Attached screenshot of access to USB port working from within the Arduino IDE.

Anyone know why I can’t access the USB port from within the Atom Platform module?
